In the past, many systems of measurement were defined on a local level, and could be based on factors as arbitrary as the length of a king's thumb. While this may work on a local level, when considering trade, as well as science, having systems of units based on units that others may not be able to relate to or understand makes interaction difficult. As such, the development of more universal and consistent systems developed over time. Today, some of the systems of units in use include the metric system, the imperial system, and the United States customary units.
The International System of Units (SI) is the standard metric system that is currently used, and consists of seven SI base units of length, mass, time, temperature, electric current, luminous intensity, and amount of substance. Although SI is used almost universally in science (including in the US), some countries such as the United States still use their own system of units. This is partly due to the substantial financial and cultural costs involved in changing a measurement system compared to the potential benefit of using a standardized system. Since US customary units (USC) are so entrenched in the United States, and SI is already used in most applications where standardization is important, everyday use of USC is still prevalent in the United States, and is unlikely to change. As such, many unit converters including this Conversion Calculator exist, and will continue to do so to ensure that people globally are able to communicate different measurements effectively.
The spread of the metric system did not occur quickly, and areas that were annexed by France during Napoleon's reign were the first to adopt the metric system. By 1875, two thirds of the European population, and nearly half the world's population had adopted the metric system. By 1920, the percentage of the world's population using the imperial system or the US customary system was 22%, with 25% using mainly the metric system, and 53% using neither.

My app is working now pretty well, but the functional tests seem to be having an issue, did I miss something maybe cos on my console in repl.it everything is fine but there are 19 tests passing and I think there should be 21: ![Screenshot_2021-01-28 boilerplate-project-metricimpconverter(3)479x500]

This online metric to imperial unit converter supports conversions from nanometers (nm), micrometers (μm), millimeters (mm), centimeters (cm), decimeters (dm), meters (m), and kilometers (km) to inches (in), feet (ft), yards (yd), miles (mi), nautical miles (M), and leagues (lea). It uses the standards defines by the International System of Units and ISO standards on quantitities and units [1][2]. The league is the only exception as it does not have an official standard.
Some imperial units continue to be used in naval and air navigation for historical reasons (the nautical mile), while others have entered through innovation, for example screen/display sizes are usually listed in inches since historically they were designed in countries using the imperial system. From the units supported by our metric to imperial converter, the league is the only one without an official definition, since it is not an official unit of length in any country.

In real life and on the Internet, there's a never-ending conflict between the two measurement systems used worldwide, the metric and the imperial systems. Which one is better? Why do Americans use feet? There are no specific answers!
It's always a shock for Europeans to come to the US and discover that at 100100100 degrees, people are only sweating and not boiling alive. Why? You will learn it with our converter from metric temperature to imperial.
The imperial system uses the Fahrenheit scale for temperature. In this case, the phenomena associated with the scale are not that straightforward. 0 F0\ \degree\mathrmF0 F corresponds to the temperature of a mixture of water and a salt. The second point required to define the scale was fixed to... the body temperature of a human, and it was fixed at 96 F96\ \degree\mathrmF96 F. Confusing? We know!
Mass has, luckily, few commonly used units: we can get over this quantity by learning just one conversion. In the metric system, we use the kilogram. Recently the definition of this unit changed from a very empirical one (a cylinder of an alloy) to a very physical one connected to quantum physics. We gladly gloss over the definition! In the imperial system, we measure mass in pounds that, for mysterious reasons, has symbol lb\mathrmlblb. We're joking: the symbol comes from the Latin name for a similar unit, the libra. The conversion between the two is the following:
These conversions are straightforward and depend on how we convert length from metric to imperial. Simply take the square or the cube of the conversion factor, and you'll find the desired conversion factors.
This online imperial to metric unit converter supports conversions from inches (in), feet (ft), yards (yd), miles (mi), nautical miles (M), and leagues (lea) to nanometers (nm), micrometers (μm), millimeters (mm), centimeters (cm), decimeters (dm), meters (m), and kilometers (km). It uses the standards defines by the International System of Units and ISO standards on quantities and units [1][2], with the league being the exception, as there is no single definition for it - we are using the U.S. standard league.
The Imperial system, sometimes referred to as the English system of units is an old system of measurements that was used throughout human history, with evidence of its use in ancient Greece, ancient Rome, the Middle ages, and more. It is currently used only in the United States, United Kingdom, and a couple of other countries, and even there it is defined by using the meter as a de facto base unit. Historically the definitions of the imperial units varied with time and place, but were set relative to the standard meter by a 1959 international treaty.
Since both systems coexist in the modern world, unit conversion is often needed when dealing with goods purchased from parts of the world using the other system. An imperial to metric converter can be helpful in such situations.

What I am looking for is a method to offer the best out of both worlds. I am looking for something that can convert all metric units into imperial and vice versa. The ideal scheme would look like this:
Edit: As per Joseph Wright's comment, a few more details:The units to convert would, at the minimum, be for weight, length, and time (with the last one optional, but advantageous). The conversion should be from standard metric (kilograms, meters, 24:00 format) to imperial (pounds, feet, 12 AM/PM format).
I realize that getting this right for every possible scenario (body height, mountain height, small distance, large distance, etc. etc.) is somewhat complex (mostly thanks to the weird parts of the imperial system).As to accuracy: Since it is not written for a scientific audience, any rounding up to the decimal point is fine. I.e.: 1 meter can easily convert into 3 feet, even if it is not really exact. Of course, if more accuracy were needed, a roundoff-point would be necessary.
But is it exactly the same in Europe and the US? Not really. Uw is expressed in metric units (W/m2K) and U-Value in imperial inch-pound units (Btu/hft2F).
Here I am faced with an issue that I believe(or at least hope) was solved 1 million times already. What I got as the input is a string that represents a length of an object in imperial units. It can go like this:
I have been trying to learn a bit more about delegates and lambdas while working on a small cooking project that involves temperature conversion as well as some cooking measurement conversions such as Imperial to Metric and I've been trying to think of a way to make an extensible Unit converter.
Because these types of conversions are two-way, you may consider setting up the interface to handle both ways, with a "ConvertBack" method or similar that will take a Temperature in the Celsius scale and convert to Fahrenheit. That reduces your class count. Then, instead of class instances, your dictionary values could be pointers to methods on instances of the converters. This increases the complexity somewhat of setting up the main TemperatureConverter strategy-picker, but reduces the number of conversion strategy classes you must define.
