Conversion Formula
The formula to convert km/h to m/s involves multiplying the speed in km/h by 0.2778. This factor comes from the fact that 1 km equals 1000 meters, and 1 hour equals 3600 seconds. So, km/h * (1000 meters / 1 km) * (1 hour / 3600 seconds) simplifies to km/h * 0.2778.
For example, converting 15 km/h: 15 * 0.2778 = 4.167 m/s. This calculation works because it adjusts the units from kilometers per hour to meters per second by applying the conversion factor.
Conversion Example
- Convert 20 km/h:
- Multiply 20 by 0.2778.
- 20 * 0.2778 = 5.556 m/s.
- This means 20 km/h equals 5.556 meters per second.
- Convert 50 km/h:
- Multiply 50 by 0.2778.
- 50 * 0.2778 = 13.89 m/s.
- So, 50 km/h is 13.89 meters per second.
- Convert 5 km/h:
- Multiply 5 by 0.2778.
- 5 * 0.2778 = 1.389 m/s.
- This indicates 5 km/h equals 1.389 meters per second.
