Speed conversion to miles per hour is inaccurate

[gerardvanderland]

Describe the bug
When using Speed conversion, you get an inaccurate result when converting to/from miles per hour.

This is caused by inaccurate cm/s value for miles per hour, 44.7 which appears in:

‎src/CalcViewModel/DataLoaders/UnitConverterDataLoader.cpp:
{ ViewMode::Speed, UnitConverterUnits::Speed_MilesPerHour, 44.7 },

as well as in ‎src/CalculatorUnitTests/Test.resw:
44.7

The accurate value is 44.704, which is (1.609344 / 3600) * 100000

Steps To Reproduce
Use Length mode and convert 1 mile to km, answer = 1.609344 km
Use Speed mode and convert 1 miles per hour to km/h, answer = 1.6092 km/h

Expected behavior
In Speed mode 1 mile per hour should convert to 1.609344 km/h

Hi @gerardvanderland, You are right about the value of 44.704.

So the expected behavior should be 1.609344 not 1,1609334. I guess you have a typo there.

[gerardvanderland]

@sravanth299, you are right, there was a typo, but also in your comment, because I had 1.1609344, not 1.1609334. :-)

Corrected the values, also to use decimal dot instead of comma.
