Samantha Nicole120 kilometers per hour (kph) equals 33.3333 meters per second (mps).
To convert 120 kph to mps, you divide the speed by 3.6, because one kilometer per hour is equal to 1,000 meters divided by 3,600 seconds, simplifying to 1/3.6 meters per second.

Conversion Formula
The conversion from kilometers per hour to meters per second is done by dividing the speed value by 3.6. This works since 1 kilometer equals 1,000 meters, and 1 hour equals 3,600 seconds. So, 1 kph = 1000 meters / 3600 seconds = 1/3.6 mps.
Formula: mps = kph ÷ 3.6
Example calculation for 120 kph:
- Start with 120 kilometers per hour
- Divide by 3.6 (since 3.6 seconds equal one hour in terms of meters and seconds)
- 120 ÷ 3.6 = 33.3333 meters per second
Conversion Example
- 60 kph to mps:
- Divide 60 by 3.6
- 60 ÷ 3.6 = 16.6667 mps
- 90 kph to mps:
- Divide 90 by 3.6
- 90 ÷ 3.6 = 25 mps
- 150 kph to mps:
- Divide 150 by 3.6
- 150 ÷ 3.6 = 41.6667 mps
- 110 kph to mps:
- Divide 110 by 3.6
- 110 ÷ 3.6 ≈ 30.5556 mps

Conversion Definitions
Kph: Kilometers per hour is a unit of speed measuring how many kilometers are traveled in one hour. It’s widely used for vehicle speeds and traffic regulations. One kph means traveling 1,000 meters each hour, which is slower than meters per second.
Mps: Meters per second is a speed unit indicating distance in meters covered per second. It’s common in science and engineering for describing velocity. One meter per second means traveling one meter every second, faster than kilometers per hour units.
Conversion FAQs
Why divide by 3.6 when converting kph to mps?
You divide by 3.6 because there are 1,000 meters in a kilometer and 3,600 seconds in an hour. Dividing 1,000 by 3,600 equals 1/3.6, so to convert kilometers per hour to meters per second, the speed value must be divided by 3.6.
Can I convert mps back to kph easily?
Yes, to convert meters per second to kilometers per hour, you multiply by 3.6. This reverses the division done before. For example, 33.3333 mps × 3.6 equals 120 kph. This two-way conversion is straightforward.
Is the conversion formula affected by units of measurement system?
No, the formula only depends on the metric system where distance is meters and kilometers, and time is seconds and hours. It won’t vary if you use metric units, but it won’t apply if you use miles or feet without adjustments.
Does the conversion change with different speeds?
The conversion factor 3.6 remains constant for all speeds in kph. Whether converting 10 kph or 200 kph, dividing by 3.6 converts the value to mps correctly. Speed magnitude doesn’t affect the formula.
Why is meters per second preferred over kilometers per hour in science?
Meters per second is preferred because it uses base units of the metric system, allowing easier calculations in physics and engineering. It simplifies formulas involving acceleration and velocity, since seconds and meters are standard SI units.
