Samantha Nicole122 kilometers per hour (kph) is equal to approximately 33.8889 meters per second (mps).
To convert speed from kilometers per hour to meters per second, you divide the value in kph by 3.6 because one kilometer equals 1,000 meters and one hour equals 3,600 seconds.

Conversion Formula
The formula to convert kilometers per hour to meters per second is:
meters per second (mps) = kilometers per hour (kph) ÷ 3.6
This works because 1 kilometer = 1,000 meters, and 1 hour = 3,600 seconds. So dividing by 3.6 converts the units from kilometers per hour to meters per second. For example, if you have 122 kph:
- Multiply by 1,000 to get meters: 122 × 1,000 = 122,000 meters
- Convert hours to seconds: 1 hour = 3,600 seconds
- Divide meters by seconds: 122,000 ÷ 3,600 ≈ 33.8889 mps
Conversion Example
Convert 85 kph to mps:
- Start with 85 kilometers per hour.
- Use the formula: mps = kph ÷ 3.6
- Calculate: 85 ÷ 3.6 = 23.6111 mps
- This means traveling at 85 kph is the same as 23.6111 meters per second.
Convert 50 kph to mps:
- Take 50 kph.
- Divide by 3.6: 50 ÷ 3.6 = 13.8889 mps
- So, 50 kph equals about 13.8889 mps.
Convert 100 kph to mps:
- Begin with 100 kph.
- Divide by 3.6: 100 ÷ 3.6 = 27.7778 mps
- This shows 100 kph converts to 27.7778 meters per second.

Conversion Definitions
kph (kilometers per hour): A unit of speed expressing the number of kilometers traveled in one hour. This measurement is often used for vehicle speeds, road limits, and weather phenomena. It combines metric distance (kilometers) with time (hours) to quantify velocity.
mps (meters per second): A speed unit representing the distance in meters traveled each second. Commonly used in physics and engineering, mps provides a metric measurement for velocity in SI units, allowing precise calculations of motion over short time intervals.
Conversion FAQs
Why divide by 3.6 when converting kph to mps?
Because 1 kilometer equals 1,000 meters and 1 hour equals 3,600 seconds, dividing the kilometers per hour value by 3.6 converts the units properly. The 3.6 comes from 3,600 seconds divided by 1,000 meters, simplifying the unit change.
Can this conversion be reversed 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 the kph to mps conversion.
Is the conversion exact or approximate?
The conversion is exact mathematically but rounding during decimal places introduces small approximations. The factor 3.6 is exact, based on fixed unit definitions.
Why is meters per second preferred in physics instead of kph?
Meters per second fit the SI system better, making equations simpler and units coherent in physics calculations. Kph is more practical for daily use like driving speeds but less convenient for scientific formulas.
Does wind or altitude affect the conversion?
The conversion itself is purely mathematical and unaffected by environmental factors. However, real speed readings might vary by such conditions, but the unit conversion formula stays unchanged.
