38 mph equals approximately 61.15 km/h.
To convert miles per hour into kilometers per hour, multiply the speed value in mph by 1.60934 because one mile equals exactly 1.60934 kilometers. So, 38 mph times 1.60934 gives the km/h equivalent, giving a more precise speed measurement in metric units.
Conversion Result and Explanation
Converting 38 mph to kmh results in about 61.15 km/h. The process involves multiplying 38 by 1.60934, the conversion factor from miles to kilometers, which is a fixed value based on the length of a mile in kilometers.

Conversion Formula
The formula to convert mph into kmh is: kmh = mph * 1.60934. This works because one mile equals 1.60934 kilometers. When you multiply mph by this number, you get the equivalent speed in km/h. For example, for 38 mph, multiply 38 by 1.60934:
- 38 x 1.60934 = 61.13932
This calculation provides the km/h value, which is the metric measurement of speed, used worldwide outside the US.
Conversion Example
- Convert 50 mph to kmh:
- Multiply 50 by 1.60934
- 50 x 1.60934 = 80.467
- Result: 50 mph equals 80.467 km/h
- Convert 20 mph to kmh:
- Multiply 20 by 1.60934
- 20 x 1.60934 = 32.1868
- Result: 20 mph equals 32.1868 km/h
- Convert 75 mph to kmh:
- Multiply 75 by 1.60934
- 75 x 1.60934 = 120.7005
- Result: 75 mph equals 120.7005 km/h
- Convert 10 mph to kmh:
- Multiply 10 by 1.60934
- 10 x 1.60934 = 16.0934
- Result: 10 mph equals 16.0934 km/h
- Convert 60 mph to kmh:
- Multiply 60 by 1.60934
- 60 x 1.60934 = 96.5604
- Result: 60 mph equals 96.5604 km/h

Conversion Definitions
mph
Miles per hour (mph) is a measurement of speed indicating how many miles a vehicle travels in one hour, used mainly in the United States and UK. It reflects the distance covered over time, and one mile equals approximately 1.60934 kilometers.
kmh
Kilometers per hour (km/h) is a metric unit of speed representing how many kilometers an object covers in an hour. It is the standard measurement for speed in most countries and is based on the metric system, where one kilometer equals 1000 meters.
Conversion FAQs
Why is the conversion factor from mph to kmh 1.60934?
The factor 1.60934 is based on the precise length of a mile in kilometers, which is exactly 1 mile = 1.60934 km. This fixed value allows accurate conversion between imperial and metric speed units, ensuring consistency across calculations.
Can I convert km/h back to mph using the same factor?
No, to convert km/h to mph, you need to divide the km/h value by 1.60934. This is because conversion is a reciprocal process, reversing the multiplication done when converting from mph to km/h.
Is there a quick way to estimate km/h from mph without a calculator?
Yes, for rough estimates, multiply mph by about 1.6. For example, 38 mph multiplied by 1.6 gives approximately 60.8 km/h, which is close enough for quick mental calculations in many cases.
What are typical speed limits in km/h for urban areas?
In many cities, speed limits in km/h range from 50 to 60 km/h, which roughly corresponds to 31 to 37 mph, depending on the country’s regulations and road conditions.
