38 mph is approximately 61.16 km/h
When converting 38 miles per hour to kilometers per hour, the result is about 61.16 km/h. This conversion helps understand speed metrics across different measurement systems.
To convert mph to km/h, you multiply the miles per hour value by 1.60934, because one mile equals approximately 1.60934 kilometers. So, 38 mph multiplied by 1.60934 gives the km/h equivalent.
What is the Conversion Result?
Converting 38 mph to km/h results in roughly 61.16 km/h. This means if a car travels at 38 miles in one hour, it covers about 61.16 kilometers in the same time. This conversion is useful for understanding speed limits and vehicle speeds internationally.

Conversion Formula
The conversion formula from miles per hour to kilometers per hour is km/h = mph × 1.60934. This works because miles and kilometers are both units of distance, but they differ in size. Multiplying the mph value by 1.60934 converts it to km/h.
For example, if you have 50 mph: 50 × 1.60934 = 80.467 km/h. Each mile is about 1.60934 kilometers, so this multiplication scales the speed appropriately.
Conversion Example
- Convert 20 mph:
- Step 1: Write down the mph value, which is 20.
- Step 2: Multiply 20 by 1.60934, resulting in 32.1868 km/h.
- Step 3: The speed in km/h is about 32.19 km/h when rounded to two decimal places.
- Convert 55 mph:
- Step 1: Take the number 55.
- Step 2: Multiply 55 by 1.60934, which gives 88.513 km/h.
- Step 3: So, 55 mph equals approximately 88.51 km/h.
- Convert 75 mph:
- Step 1: Use the number 75.
- Step 2: Multiply 75 by 1.60934, resulting in 120.7005 km/h.
- Step 3: Speed is about 120.70 km/h in km/h.

Conversion Definitions
mph
mph stands for miles per hour, a measurement of speed used mainly in the United States and the United Kingdom. It indicates how many miles a vehicle travels in one hour, representing a distance over time in imperial units.
kmh
kmh, or kilometers per hour, is a metric measurement of speed showing how many kilometers are traveled in one hour. It’s commonly used worldwide, especially in countries using the metric system, to express vehicle and travel speeds.
Conversion FAQs
How do I convert 38 mph to km/h without a calculator?
To convert 38 mph to km/h manually, multiply 38 by 1.60934, which gives about 61.16 km/h. This multiplication accounts for the difference in units, translating miles to kilometers, and is straightforward once you memorize the factor.
Why is km/h used more widely outside the US?
Km/h is preferred in most countries because they use the metric system, which simplifies unit conversions and standardizes measurements across regions. The US uses mph mainly because of historical and legal reasons associated with imperial units.
Can I convert km/h back to mph using the same formula?
Yes, to convert km/h to mph, divide the km/h value by 1.60934. For example, 61.16 km/h divided by 1.60934 equals approximately 38 mph, reversing the conversion process accurately.
