The conversion of 38 mph equals approximately 61.1552 km/h.
To convert miles per hour to kilometers per hour, multiply the mph value by 1.60934. This is because 1 mile equals 1.60934 kilometers, so the conversion factor is used to change the units from miles to kilometers, giving the speed in km/h.
Conversion Result and Explanation
38 miles per hour is roughly 61.1552 kilometers per hour. To reach this, I multiplied 38 by 1.60934. This calculation converts the miles into kilometers and retains the same speed measurement in the metric system, making it easier to compare or understand in countries using km/h.

Conversion Formula
The formula to convert mph to kmh is: kmh = mph × 1.60934. It works because 1 mile equals 1.60934 kilometers, so multiplying the speed in miles per hour by this factor gives the equivalent speed in kilometers per hour. For example, 38 mph multiplied by 1.60934 is 61.1552 km/h.
Conversion Example
- Convert 20 mph to kmh:
- Multiply 20 by 1.60934
- 20 × 1.60934 = 32.1868 km/h
- Convert 50 mph to kmh:
- Multiply 50 by 1.60934
- 50 × 1.60934 = 80.467 km/h
- Convert 70 mph to kmh:
- Multiply 70 by 1.60934
- 70 × 1.60934 = 112.6538 km/h
- Convert 100 mph to kmh:
- Multiply 100 by 1.60934
- 100 × 1.60934 = 160.934 km/h
- Convert 15 mph to kmh:
- Multiply 15 by 1.60934
- 15 × 1.60934 = 24.1401 km/h

Conversion Definitions
mph
Miles per hour (mph) is a unit measuring speed indicating how many miles are traveled in one hour, used primarily in the United States and the UK for vehicle speeds, with 1 mph roughly equal to 1.60934 km/h.
kmh
Kilometers per hour (km/h) is a metric speed unit representing how many kilometers are covered in an hour, standard in most countries outside the US, with 1 km/h equal to approximately 0.621371 mph.
Conversion FAQs
What is the difference between mph and kmh?
The main difference is the measurement units: mph measures miles per hour, mainly used in the US and UK, while km/h measures kilometers per hour, common elsewhere. They indicate the same concept of speed but in different units.
Why is the conversion factor 1.60934 used?
This factor is based on the exact length of a mile in kilometers, where 1 mile equals 1.60934 km. It ensures precise conversion between the imperial and metric systems, maintaining consistency in speed calculations.
Can I convert km/h back to mph using the same formula?
Yes, but you need to divide km/h by 1.60934 to get mph. The formula for km/h to mph is: mph = km/h ÷ 1.60934, reversing the conversion process.
Is there a simple way to estimate kmh from mph without a calculator?
For rough estimates, multiply mph by 1.6. For example, 38 mph is approximately 61 km/h, which is close enough for general purposes when precision isn’t critical.
How accurate is the conversion from mph to kmh?
The conversion using 1.60934 is highly accurate for most practical purposes, with negligible error for everyday speed conversions. For highly precise scientific calculations, use the full factor.
