Conversion Formula
The conversion from mph to kmh is based on multiplying the mph value by 1.60934. This works because 1 mile equals 1.60934 kilometers, so to find km/h, you convert miles to kilometers directly. For example, to convert 9 mph:
- Start with 9 mph.
- Multiply 9 by 1.60934.
- 9 × 1.60934 = 14.48406 km/h.
This formula ensures that the speed in km/h accurately reflects the miles per hour measurement by applying the precise conversion factor.
Conversion Example
- Convert 15 mph to km/h:
- Multiply 15 by 1.60934.
- 15 × 1.60934 = 24.1401 km/h.
- Convert 5 mph to km/h:
- Multiply 5 by 1.60934.
- 5 × 1.60934 = 8.0467 km/h.
- Convert 20 mph to km/h:
- Multiply 20 by 1.60934.
- 20 × 1.60934 = 32.1868 km/h.
- Convert 0 mph to km/h:
- Multiply 0 by 1.60934.
- 0 × 1.60934 = 0 km/h.
- Convert 50 mph to km/h:
- Multiply 50 by 1.60934.
- 50 × 1.60934 = 80.467 km/h.

Conversion Definitions
mph: Miles per hour (mph) is a unit measuring how many miles are traveled in one hour. It is commonly used in the United States and UK to express vehicle speed or travel velocity.
kmh: Kilometers per hour (km/h) indicates how many kilometers are covered in one hour. It is the standard speed measurement in most countries worldwide, especially outside the US and UK.
Conversion FAQs
Why does converting mph to km/h involve multiplication?
The multiplication by 1.60934 reflects the conversion factor between miles and kilometers. Since 1 mile equals 1.60934 km, multiplying mph by this factor gives the equivalent speed in km/h, ensuring precise conversion.
Can I use a simple approximation for quick conversions?
Yes, for rough estimates, multiplying mph by 1.6 gives a close approximation to km/h. For example, 9 mph times 1.6 equals 14.4 km/h, which is very close to the exact 14.484 km/h value, but for exact calculations, use 1.60934.
Does the conversion work for negative speeds too?
Absolutely, negative speeds represent reverse motion and are converted the same way. For example, -9 mph times 1.60934 equals approximately -14.484 km/h, indicating reverse velocity in km/h units.
Is the conversion factor the same for all speed measurements?
Yes, the factor 1.60934 remains constant for converting miles to kilometers. It applies uniformly across all mph values, regardless of the magnitude, to ensure consistent and accurate conversions.
