100 kilometers per hour (kph) equals approximately 27.7778 meters per second (mps).
To convert 100 kph to mps, you divide the speed value by 3.6 because one kilometer per hour is equal to 1,000 meters divided by 3,600 seconds. This changes the unit from kilometers per hour to meters per second, which is a standard unit for velocity in physics.

Conversion Formula
The formula for converting kilometers per hour (kph) to meters per second (mps) is:
mps = kph ÷ 3.6
This works because 1 kilometer equals 1,000 meters, and 1 hour equals 3,600 seconds. So to convert from kilometers per hour to meters per second, you change the units by dividing by 3,600 seconds and multiplying by 1,000 meters. Simplifying the fraction 1000/3600 results in 1/3.6.
Example calculation for 100 kph:
- Start with 100 kph
- Divide 100 by 3.6
- Result: 100 ÷ 3.6 = 27.7777 mps
Conversion Example
- 50 kph to mps
- Take 50 kph
- Divide by 3.6
- 50 ÷ 3.6 = 13.8889 mps
- 80 kph to mps
- 80 divided by 3.6
- 80 ÷ 3.6 = 22.2222 mps
- 120 kph to mps
- 120 divided by 3.6
- 120 ÷ 3.6 = 33.3333 mps
- 90 kph to mps
- Divide 90 by 3.6
- 90 ÷ 3.6 = 25.0000 mps

Conversion Definitions
kph: Kilometers per hour is a unit of speed measuring the number of kilometers traveled in one hour. It is commonly used in transportation and vehicle speed limits, representing how fast an object moves over a distance within an hour of time.
mps: Meters per second is a standard unit of velocity in the International System of Units (SI), indicating how many meters an object moves in one second. It is preferred in scientific calculations for precise measurements of speed.
Conversion FAQs
Why do we divide by 3.6 to convert kph to mps?
Because 1 kilometer equals 1,000 meters and one hour equals 3,600 seconds, dividing by 3.6 converts the distance and time units simultaneously. This converts from kilometers per hour to meters per second, matching the SI unit for speed.
Can I convert mps back to kph easily?
Yes, to convert meters per second back to kilometers per hour, multiply the mps value by 3.6. This reverses the division done during kph to mps conversion, restoring the original speed unit.
Is the conversion exact or approximate?
The conversion using division by 3.6 is exact because it is based on fixed unit definitions. However, rounding decimals in calculations can cause slight approximations in displayed results.
Why use meters per second instead of kilometers per hour?
Meters per second is used mostly in scientific contexts and physics because it matches the base SI units which makes calculations easier when combining with other SI units like meters and seconds.
Does temperature or weather affect kph to mps conversion?
No, the conversion between kph and mps is purely mathematical based on units and unaffected by external factors like temperature or weather conditions.
