Understanding the Conversion from km/hr to m/s
When converting speed from kilometers per hour (km/hr) to meters per second (m/s), the formula you can use is based on the relationship between kilometers and meters, as well as hours and seconds.
Why Use the 5/18 Formula?
- 1 km = 1000 meters: This is a standard metric conversion.
- 1 hour = 3600 seconds: There are 3600 seconds in an hour.
To convert km/hr to m/s, you can derive the conversion factor:
- Conversion Factor:
- 1 km/hr = (1000 meters) / (3600 seconds) = 1/3.6 m/s
- This simplifies to the multiplication factor: 5/18.
Steps to Convert Using the 5/18 Formula
1. Identify the Speed: Start with the speed in km/hr that you want to convert.
2. Apply the Formula: Multiply the speed by 5/18.
- Formula: Speed in m/s = Speed in km/hr × (5/18)
3. Calculate: Perform the multiplication to get the result in m/s.
Example of Conversion
- If the speed is 90 km/hr:
- Calculation:
- Speed in m/s = 90 × (5/18)
- Speed in m/s = 25 m/s
Conclusion
Converting km/hr to m/s is straightforward using the 5/18 formula. This conversion is crucial in various fields such as physics and engineering, where consistent units are necessary for calculations. Remember, simply multiply your km/hr value by 5/18 to achieve the conversion to m/s.
