Conversion Formula

To convert meters per second (m/s) to kilometers per hour (km/h), use the following formula:

Kilometers per hour = Meters per second × 3.6

Explanation:

• 1 kilometer = 1000 meters
• 1 hour = 3600 seconds
• The formula accounts for both converting meters to kilometers and seconds to hours.

So, to convert from meters per second to kilometers per hour, simply multiply by 3.6.

Conversion Table: Meters per Second to Kilometers per Hour

Here is a quick reference table for converting meters per second (m/s) to kilometers per hour (km/h):

Meters per Second (m/s)	Kilometers per Hour (km/h)
1	3.6
2	7.2
5	18
10	36
20	72
50	180
100	360
200	720

Quick Conversion Example

Let’s say you have a speed of 15 meters per second (m/s) and want to convert it to kilometers per hour (km/h).

Kilometers per hour = 15 × 3.6 = 54 km/h

So, 15 meters per second is equivalent to 54 kilometers per hour.

Frequently Asked Questions (FAQs)

1. How do I convert kilometers per hour to meters per second?

To convert kilometers per hour (km/h) to meters per second (m/s), use the inverse formula:

Meters per second = Kilometers per hour ÷ 3.6

For example, if you have 72 km/h:

Meters per second = 72 ÷ 3.6 = 20 m/s

2. Why do we multiply by 3.6 in this conversion?

The factor of 3.6 comes from the relationship between meters and kilometers (1000 meters = 1 kilometer), and seconds and hours (3600 seconds = 1 hour). The number 3.6 is the result of dividing 3600 by 1000.

3. Can I use an online converter for this?

Yes! Online converters are an excellent way to quickly convert meters per second to kilometers per hour. Just enter your value in meters per second, and you’ll get the result in kilometers per hour instantly.

4. Where is this conversion typically used?

This conversion is commonly used in fields like physics, engineering, transportation, and meteorology, especially when measuring speeds or velocities in different units, such as car speeds (km/h) or wind speeds (m/s).
