The conversion of 15 km/h to meters per second (ms) results in 4.1667 ms.
This occurs because 1 km/h equals approximately 0.2778 meters per second. To convert, you multiply the speed in km/h by 0.2778. So, for 15 km/h: 15 × 0.2778 = 4.1667 ms, giving a precise measure of how fast the object is moving per second.

Conversion Formula
The formula to convert km/h to m/s is to multiply the speed in kilometers per hour by 0.2778. This works because there are 1000 meters in a kilometer and 3600 seconds in an hour, so km/h divided by 3.6 gives m/s. Mathematically: km/h ÷ 3.6 = m/s.
- Suppose the speed is 15 km/h.
- Divide 15 by 3.6.
- 15 ÷ 3.6 = 4.1667 m/s.
Conversion Example
- Convert 25 km/h to m/s:
- Divide 25 by 3.6.
- 25 ÷ 3.6 = 6.9444 m/s.
- Convert 10 km/h to m/s:
- Divide 10 by 3.6.
- 10 ÷ 3.6 = 2.7778 m/s.
- Convert 50 km/h to m/s:
- Divide 50 by 3.6.
- 50 ÷ 3.6 = 13.8889 m/s.

Conversion Definitions
“kmh” means kilometers per hour, a speed measurement indicating how many kilometers an object travels each hour, used frequently in transportation and speed limits. “ms” stands for meters per second, a metric unit measuring how many meters an object moves every second, often used in physics and engineering.
Conversion FAQs
Why do we divide km/h by 3.6 to get m/s?
Because 1 km equals 1000 meters, and 1 hour equals 3600 seconds. Dividing km/h by 3.6 simplifies the conversion, directly translating kilometers per hour into meters per second, making calculations straightforward for speed comparisons.
Can I convert km/h to m/s without a calculator?
Yes, by using the approximate factor 0.2778. You multiply the km/h value by 0.2778 to get m/s. For example, 15 km/h times 0.2778 equals about 4.1667 m/s, which is close enough for most practical purposes without needing precise calculations.
Is the conversion from km/h to m/s linear?
Yes, because the formula involves multiplying by a constant (0.2778), the relationship between km/h and m/s is linear. Doubling km/h doubles m/s, and halving km/h halves m/s, making it predictable and proportional.
How accurate is the 0.2778 conversion factor?
The factor 0.2778 is rounded from the exact value 1/3.6. For most everyday uses, this rounding does not significantly affect the results. For high-precision scientific calculations, use the exact fraction 1/3.6 or more decimal places.
Where is this conversion used in real life?
This conversion is common in physics, engineering, and transportation to compare speeds measured in different units. For example, converting car speeds from km/h to m/s in vehicle dynamics or physics experiments.
