The conversion factor is 1.6 kilometers for each 1 mile.
100 kph = 62.1 mph
220 km/h is about 136.7 mph
55km/h=34.175415573034996mph =34.2mph
Divide kph by 1.609 to get mph.(Same as you would do with kilometers to get miles.)Of course, you may find it easier to mentally multiplythe kph by 0.6214, which is the same operation, and for a ballpark figure you can use 0.62 for most speeds. Example : 80 kph is about 50 mph.
Since kilometers are bigger than miles, 60 km per hour would be faster
27.96 mph
50 mph is 31.07 kph.
46 kph = about 28.6 mph
25 mph = about 40.233 kph
43 mph = 69.2 kph
195 kph is approximately 121 mph.
35 kph is 21.75 mph.35 kph = 21.75 mph
340 kph = 211.26 mph
24 kph = about 15 mph. (14.9129086 mph)
To convert kilometers per hour (kph) to miles per hour (mph), you can use the formula: 1 kph = 0.621371 mph. So, to convert kph to mph, you simply multiply the speed in kph by 0.621371.
165 mph = 265.54 kph (rounded)
250 mph = 402.34 kph.
