Conversion Formula
The formula to convert mph to kmh multiplies the speed in miles per hour by 1.60934, because 1 mile equals 1.60934 kilometers. This works because it scales the miles to kilometers directly. For example, 1 mph is 1 * 1.60934 = 1.60934 km/h. For 38 mph, multiply 38 by 1.60934: 38 * 1.60934 = 61.15692 km/h.
Conversion Example
- Convert 50 mph to kmh:
- Step 1: Write down the mph value: 50
- Step 2: Multiply 50 by 1.60934: 50 * 1.60934
- Step 3: Calculate: 80.467 km/h
- Result: 50 mph equals approximately 80.467 km/h.
- Convert 20 mph to kmh:
- Step 1: Write down the mph value: 20
- Step 2: Multiply 20 by 1.60934: 20 * 1.60934
- Step 3: Calculate: 32.1868 km/h
- Result: 20 mph is roughly 32.1868 km/h.
- Convert 100 mph to kmh:
- Step 1: Write down 100
- Step 2: Multiply 100 by 1.60934: 100 * 1.60934
- Step 3: Calculate: 160.934 km/h
- Result: 100 mph converts to about 160.934 km/h.

Conversion Definitions
mph: Miles per hour measures how many miles are covered in one hour. It is used mainly in the United States and UK to indicate vehicle speeds, representing the distance traveled over time in a standard unit of miles per hour.
kmh: Kilometers per hour measures the distance in kilometers traveled in one hour, used in most countries outside the US for speed limits, vehicle speeds, and transportation, based on the metric system for measuring distance over time.
Conversion FAQs
Why is mph multiplied by 1.60934 to get kmh?
This multiplication converts miles to kilometers because 1 mile equals 1.60934 kilometers. Multiplying the speed in mph by this factor scales the miles to kilometers, giving the equivalent speed in km/h.
Can I use a simple rounded number for quick conversions?
Yes, for rough estimates, using 1.6 as the conversion factor is often sufficient. For example, 38 mph times 1.6 equals about 60.8 km/h, close enough for casual purposes but less precise for official or technical needs.
Is 61 km/h the exact conversion for 38 mph?
Close, but not exact. The precise value is approximately 61.15692 km/h. Rounding to 61 km/h simplifies the number but slightly reduces accuracy, which is acceptable in everyday contexts.
What does the conversion factor 1.60934 represent?
This factor is the exact number of kilometers in one mile. It is used in conversions between imperial and metric speed measurements, ensuring precise and consistent transformations.
How accurate is the conversion for high speeds?
The formula remains accurate regardless of speed, but small rounding differences can occur, especially with less precise factors. For high speeds, using the exact 1.60934 factor ensures accuracy in calculations.
