Convert Miles To Km
Merlyn Goedecke
History/origin: The mile is an English unit (predecessor of Imperial units and United States Customary Units) of length. The use of the abbreviation "m" for mile was common before the widespread adoption of the metric system; after the adoption of the metric system, "mi" became the preferred abbreviation in order to avoid confusion between miles and meters. The definition of a mile as 5,280 feet (or 8 furlongs), sometimes referred to as the statute mile, international mile, or land mile, which differs from the Roman mile of 5,000 feet, developed due to the importance of the furlong in England, back in 1593. There also exist a number of units based on, or closely related to, the Roman mile, including the nautical mile (1.852 km exactly), Italian mile (1.852 km), and the Chinese mile (500m exactly).
Current use: Although most countries have adopted the metric system and use kilometers, rather than miles, to express land distance, the mile is still prevalently used in countries such as the United States (US), United Kingdom (UK), Myanmar, and Liberia, as well as some other countries which are either US or UK territories, or have historical ties with either country.
Current use: It is currently the official unit of measurement for expressing distances between geographical places on land in most of the world. However, there still remain a number of countries that primarily use the mile instead of the kilometer including the United States and the United Kingdom (UK). Unlike the United States, the UK has adopted the metric system; while the metric system is widely used in government, commerce, and industry, remnants of the imperial system can still be seen in the UK's use of miles in its road systems.
It works fine with round when I give exact number like 5280 Feet = 1 Miles but when I give some approx number like 6200 Feet it save 1.23 Miles in db and during fetch in convert like 6177.60 so it sound like there is problem in conversion because actual value change from 6200 to 6177.60.
Second problem If I remove round before saving database then it save 5280 Feet = 0.99999999792 miles in db and it create problem during back end calculation which need exact miles value and we can't apply round there.
Sometimes it's useful to be less rigorous about how one expresses units of measurement while still being strict about the way the conversions are performed. Here is an example where a single method takes a string as input, and returns an appropriate floating-point value for predefined units such as kilometers or miles while remaining flexible about the way the distance units are expressed.
I am trying to convert the lat and long coordinates I have into nautical miles. I read here that I had to convert my lat and long (in degrees) to radians which I did by using the =RADIANS function. My situation is as follows:
@mtarler Thanks for trying to help. I don't think you're answer is very clear or actionable. Either way, I succeeded in converting my coordinates into radians. From there I found two formulas to convert those coordinates into miles.
The second formula I found here and could be retrieved by downloading the spreadsheet. I believe the second formula (utilized the 'P-Theorum' you discussed in your answer which) in this case solves for the radius of the earth in miles =3958.82*((2*ASIN(SQRT((SIN((N2-R2)/2)^2)+COS(N2)*COS(R2)*(SIN((O2-S2)/2)^2))))).
Even if we would compare the direct distance (0.354mi) results given by Google Maps and then compare them to the results received by the output of our two formulas there is also a slight difference. With the nautical miles formula output of 0.327mi and formal miles output of 0.376mi. As you can see, there are still slight differences between both results. However, when comparing the actual navigatable distance (0.5mi), there is an even larger discrepancy which could definitely skew results.

Miles to meters conversion involves changing the unit of distance from miles to meters. 1 mile is approximately equal to 1609.34 meters. Miles to meters conversion involves a simple multiplication where you multiply the number of miles by 1609.34 to get the equivalent distance in meters.
Road signs in most countries that use the metric system are displayed in kilometers. Kilometers (km) are metric length units that are used to depict larger distances on road signage. Distances between cities, towns, or highway exits, are often displayed on road signs in kilometers. For example, a distance of 100 kilometers is about equivalent to 62 miles.
Nautical miles are a unit of measurement used to measure distances across water or through the air in navigation, maritime, and aviation applications. The word \\\"nautical\\\" comes from the Latin word nauticus, which means \\\"pertaining to ships\\\" or \\\"seafaring.\\\"
I am using the following code: I want my circles to truly reflect the radiuses from a certain coordinate. In my data set I have my Max.Distance.from.C.or.HB (which is the radius of the person from the coordinate) in miles. Do I need to make any conversion to the radius in my code?
To convert miles per minute to miles per hour, you need to multiply the number of miles per minute by the number of minutes in an hour. Since there are 60 minutes in an hour, divide the number of miles per minute by 60 to get the number of miles per hour. For example, if you have 10 miles per minute, divide that number by 60 to get 0.167 miles per hour.
And if you have a card that earns Capital One miles, you have one more reason to add a Capital One cash-back card to your wallet. With the right card pairing, you can turn your Capital One cash-back rewards into transferable miles, making them even more valuable.
Ideally, you want to pair a fixed-rate earning card with a card that has bonus categories. Since all eligible Capital One miles-earning cards earn at a flat rate, your best option is to pair one of them with a card in the Savor family since they earn bonus rewards on spending in specific categories.
If, for example, you have the Capital One Venture Rewards Card, you earn a solid 2 miles per dollar on all your purchases. If you also have the Capital One Savor card, you can earn an impressive 4% back on dining, entertainment, popular streaming services and grocery store purchases.
The Capital One VentureOne Rewards Credit Card only earns 1.25 miles per dollar on every purchase but offers the same redemption options as the Venture Rewards for no annual fee (see rates and fees). The Capital One SavorOne Cash Rewards Credit Card offers 3% cash back on dining, entertainment, popular streaming services and at grocery stores (excluding superstores like Walmart and Target), plus 1% on all other purchases, also for no annual fee (see rates and fees).
You can earn even more Capital One miles if you hold a cash-back Capital One card and a card that earns miles. With both, you can combine your rewards and unlock the ability to transfer your rewards to Capital One's full range of hotel and airline transfer partners. If you play your cards right, your cash-back card just might become your wallet's secret earning weapon.
