The great thing about QGIS is that it is really a "meta-GIS" as it gives you access to multiple GIS technologies under the hood. So, there is yet a third raster calculator for you to play with that also gives you control over the pixel depth. This is the SAGA raster calculator (also in the Processing Tool Box (go: Processing toolbar -> SAGA -> Raster Calculus -> Raster Calculator).
As to your final point, most of the GDAL functions under the hood can save with creation options set to a variety of compression options. However, to do that you often need to use the command line (or 'Warp'/'Transform'). There used to be functionality to edit the GDAL command before issuing it in QGIS, but it has been removed and repeated requests to put it back have been rejected. We never did have that with the raster calculator though. I guess what I am saying is that QGIS is a convenience GUI for multiple GIS software packages and sometimes you may need to revert to the good ol' commandline (if you have QGIS installed, then you also have access to all the OGR/GDAL commandline modules). BUT the good news is that you CAN specify these creation options if you use the GDAL Raster Calculator in Processing Tool Box (see the Advanced Parameters in the dialog box and refer to GDAL documentation for what these should be).
Based on the official Unit Conversion Tables, the Bytes Calculator converts computer data from megabytes to gigabytes, kilobytes and even terabytes quickly and easily. For more information on the value of bytes, consult the following conversion chart:
This page uses the traditional definition where one kilobyte is 1024 bytes, one megabyte is 1024 kilobytes, and so on. If you want to convert the prefixes as they are defined by the International System of Units (SI), were each step is worth 1000 instead of 1024, you will have to use a SI prefix converter tool instead.
A computer can normally not operate directly on chunks of data that are smaller than one byte. Historically the number of bits in a byte could vary depending on the computer hardware, but nowadays it is as good as always a synonym for 8 bits which is also the assumption on this page.
This javascript featured website calculates the CRC value from an input string or an input byte string.
Several common CRC instance predefined and available from a list. Furthermore, the definition of own CRC instances is supported by specifying:
2023/06/19: Fixed a bug when there is a trailing space in binary string input.
2019/02/12: Added the support for 64bit CRC calculation and for binary string input.
2016/11/11: Added the option to print the CRC lookup table 'reversed'.
2016/07/27: Fixed a bug: A hexadecimal value with more than two digits after the "0x" is not correctly parsed. This could have resulted in the fact that the calculated CRC value of 0x01 differs to e.g. of 0x0001. Please note the added description above about input data. Thanks to Matthew Reed for pointing the issue to me.2016/07/09: Fixed a bug: When the input data was given as bytes, then the number of whitespaces had an influence on the result. E.g the CRC value of "0x31 0x32" and "0x31 0x32" (note the additional space character) were not the same. The fix now shall ignore all number and kinds of whitespace characters and take only the byte values into account. Thanks to Alan Ott Goodman for pointing the issue to me.
2016/03/09: Fixed a bug: Sometimes a CRC32 result value was printed with only seven digits! A zero was then missing, e.g. the printed result was 0xC6FF2F8 instead of the correct one 0xC6FF02F8. Thanks to David Goodman for pointing the issue to me.

scriptSig (varies) The source of witness data for legacy UTXOs.This data is used to prove that the transaction is authorized bysomeone controlling the appropriate private keys. For the templatesused by this calculator, the scriptSigs sizes are:
Witness item count (compactSize/4) The number of witnesselements. This field is included for each input if the transactioncontains at least one segwit input. 0.25 vbytes for up to 252 elements
Witness items (varies) The source of witness data in segwittransactions. This data is used to prove that the transaction isauthorized by someone controlling the appropriate private keys.Each item is prefixed by a compactsize size() identifier. Forthe templates used by this calculator, the witness data sizes are:
The list below indicates the size in bytes of common elements used inthe scripts above. When used in a scriptPubKey or a scriptSig, the sizein vbytes is the same as the size in bytes. When used as witness datain a segwit input, the size in vbytes is the size in bytes divided byfour.
1 byte is equal to 0.000001 megabytes = 10-6 megabytes in base 10 (decimal) in SI.
1 byte is also equal to 0.00000095367432 megabytes = 2-20 megabytes in base 2 (binary) system.
Byte is the basic unit of digital information transmission and storage, used extensively in information technology, digital technology, and other related fields. It is one of the smallest units of memory in computer technology, as well as one of the most basic data measurement units in programming. The earliest computers were made with the processor supporting 1 byte commands, because in 1 byte you can send 256 commands. 1 byte consists of 8 bits, which go together as one unit in storage, processing or transmission of digital information.
Megabyte (MB) is a unit of transferred or stored digital information, which is extensively used in information and computer technology. In SI, one megabyte is equal to 1,000,000 bytes. At the same time, practically 1 megabyte is used as 220 B, which means 1,048,576 bytes. Nowadays, the amount of information measured by megabytes is used for representing the size of a typical MP3 file, the size of a JPEG image, and so on.
This calculator can be used to compute a variety of calculations related to bandwidth, including converting between different units of data size, calculating download/upload time, calculating the amount of bandwidth a website uses, or converting between monthly data usage and its equivalent bandwidth.
Use this calculator to estimate the bandwidth needs or actual data usage of a website. Be sure to include the bot traffic (Google bots, Bing bots, etc.) as well as other connection needs. Often the bots use more bandwidth than real users.
The amount of bandwidth a person or company needs is entirely dependent on how they plan to use the Internet. Streaming or hosting large amounts of video, for example, requires far more bandwidth than simply browsing the Internet. The above calculators can be used to make estimations based on potential needs.
Hi Jodyfsu,
Thank you for the search query simplification. since i have 3 fields such as bytes,bytes_in and bytes_out but in the above search it only bytes/1024, does it mean bytes will capture the total data of both incoming and outgoing? secondly the final one stats sum(GB) so i don't want it to group by either user or host i just wanted to get total Banwidth so doing stats sum(GB) will give the over all BandWidth i think. Kindly correct me if I am wrong on any of thing explained above.
About the Bits/Bytes Calculator
The SG Bits/Bytes Conversion Calculator is a tool provided for quick conversion of bits/bytes, etc. To use the calculator just fill in a number in the appropriate field, and all other values will be calculated automatically. For additional information, please read our Bits, Bytes & Bandwidth Quick Reference article.
Because of computer architecture and memory address boundaries, bytes are usually some multiple or exponent of two.However, the terms Bytes, Megabytes and Gigabytes are often used ambiguously. Whether values are calculated using the decimal or binary systems depends on the context.For example, most hard disk drive and flash-memory manufacturers define 1 gigabyte as a million bytes (decimal gigabyte, 109), while computer operating systems usually calculate drive/file/RAM size in binary gigabytes (230).
In computer networking the conventional SI decimal units are followed. Manufacturers of networking equipment always use 1000-bit kilobits as their basic unit of measurement.
If you are young enough, then you've had electronic calculators all your life, and the way you would do any calculation is simply to enter it into the calculator. So when you learned physics, in particular, you'd just take the physical formula and enter the actual values. For example, the period of a pendulum is given by:
Before there were electronic calculators there were mechanical calculators, like the one pictured. The simplest operations were to add and subtract. You would zero out the total, enter a number, turn the handle, enter the next number, turn the handle again, and so on. You could work your way down a column of figures and add them all up. To subtract, you turned the handle the other way. You couldn't do multiplication or division directly.
The calculators actually had a movable carriage to hold the total, and you could use that to do multiplication by repeated addition. To calculate, for example, 257 74563, you would enter the longest number 74563, With the carriage fully to the left (units position), you'd turn the handle seven times, then move the carriage one space to the right to the tens position, turn the handle five times, move the carriage once more, and then turn the handle twice. You could then read out the answer. I think the other number, that kept track of the handle turns, should now read the other number, 257, to confirm that you did it correctly.
Electromechanical calculators would automate this process for multiplication and division. Division, in particular, was impressive, subtracting until the number "carried" to all 9s, adding the overshoot back in again, and then moving the carriage, and repeating. Remember, there is zero electronics (transistors) in this machine. The school I went to had exactly one machine like this, and a few manual machines. For everything else, there were log tables and slide rules.
