In this case google gives you:

Another contributor says:
The first answer, above, will certainly do the trick. But I'm very bothered by any answer
that says "You solve this arithmetic problem by keying the numbers into the machine and
reading what comes out."
If the questioner adopts this technique, then
A). S/he'll never learn anything.
B). S/he won't recognize the garbage that comes out of the machine when s/he makes
a mistake keying the problem into it.
C). S/he'll be at a complete and total loss if s/he needs an answer and doesn't happen to
have a computer and internet access available at the moment.
Please accept the following slightly more useful answer, in lieu of going through the
complete derivation:
In order to convert kilometers to miles, or kilometers per hour to miles per hour ...
Divide by 1.6093
Algebraic Steps / Dimensional Analysis Formula 50 km/hr*1000 m/hr
1 km/hr*3.2808 ft/hr
1 m/hr*1 mi/hr
5280 ft/hr=31.06855961 mi/hr
Direct Conversion Formula 50 km/hr*1 mi/hr
1.609344 km/hr=31.06855961 mi/hr
To convert miles to kilometers, multiply by 1.6. The same if you want to convert miles/hour to kilometers/hour.
Divide km per hour by 1.609
roughly MPH X 1.609
70 miles per hour is 112 kilometers per hour. The formula to convert miles to km 70 mi* 1.609344 km 1 mi = 112.65408 km
To convert miles per hour to kilometres per hour, multiply by 1.609344. Therefore, 187 miles per hour is equal to 187 x 1.609344 = 300.947328 kilometres per hour.
To convert miles to kilometers, multiply by 1.6. The same if you want to convert miles/hour to kilometers/hour.
48.28kph
Conversion: mph x 1.6093 = kilometers per hour
Divide km per hour by 1.609
You cannot convert 25 "kilometers" as a length measure in miles per hour as a speed. 25 kilometers per hour are 15.5 miles per hour.
Multiply miles per hour (mph) by 1.609 to get kilometers per hour (km/h)
Multiply the mph by 1.609
1 Kilometer per Hour = 0.621371192237334 Miles per Hour.So, multiplying it to km/hr we can get mile/hr.
Multiply miles per second by 5,793 to get kilometers per hour. (mps x 5793 = kph)
Multiply miles per hour by 1.60934 to get km per hour.
Suggestion: Convert miles to kilometers, then it should be easy to compare. One mile is about 1.6 kilometers.
One kilometer per hour = 0.621371 miles per hour so: Kph x 0.621371=Mph
