120 kilometers per hour (kph) is equal to 33.3333 meters per second (mps).

This conversion result comes from changing the speed unit from kilometers per hour to meters per second, by dividing the value in kph by 3.6. Since 1 kilometer equals 1000 meters and 1 hour equals 3600 seconds, the factor 3.6 converts kph to mps.

Conversion Formula

The formula for converting kilometers per hour to meters per second is:

mps = kph ÷ 3.6

This works because 1 kilometer equals 1000 meters, and 1 hour equals 3600 seconds. To convert km/h to m/s, you divide the number of kilometers by the number of seconds in an hour:

• 1 kph = (1000 meters) / (3600 seconds)
• = 1000 / 3600 mps
• = 1 / 3.6 mps

For example, for 120 kph:

• 120 ÷ 3.6 = 33.3333 mps

So, 120 kilometers per hour equals 33.3333 meters per second.

Conversion Example

• Convert 90 kph to mps:
  • Start with 90 kph
  • Divide 90 by 3.6
  • 90 ÷ 3.6 = 25 mps
  • Therefore, 90 kph equals 25 meters per second
• Convert 60 kph to mps:
  • Begin with 60 kilometers per hour
  • Calculate 60 ÷ 3.6
  • 60 ÷ 3.6 = 16.6667 mps
  • This means 60 kph is 16.6667 meters per second
• Convert 135 kph to mps:
  • Take the speed 135 kph
  • Divide by 3.6 to convert
  • 135 ÷ 3.6 = 37.5 mps
  • So, 135 kilometers per hour equals 37.5 meters per second
• Convert 100 kph to mps:
  • Start from 100 kilometers per hour
  • Divide by 3.6
  • 100 ÷ 3.6 = 27.7778 mps
  • 100 kph is equal to 27.7778 meters per second

Conversion Definitions

kph (kilometers per hour): Kilometers per hour is a unit of speed expressing how many kilometers an object travels in one hour. It is often used for road speed limits and vehicle speeds. One kph equals 1000 meters traveled in 3600 seconds.

mps (meters per second): Meters per second is a metric unit of speed showing how many meters an object moves every second. It is commonly used in physics and engineering for precise speed measurements. One mps equals one meter traveled in one second.

Conversion FAQs

Why divide by 3.6 to convert kph to mps?

Since 1 kilometer equals 1000 meters and 1 hour equals 3600 seconds, dividing by 3.6 converts the distance and time units correctly. This ratio simplifies from 1000/3600, giving 1/3.6, which transforms kph into mps.

Can I use this conversion for any speed value?

Yes, the formula is valid for all speeds measured in kilometers per hour. Whether the speed is low or high, dividing by 3.6 always provides the equivalent in meters per second accurately.

Why is meters per second preferred in physics?

Meters per second is preferred because it uses base SI units for length and time, making calculations easier and more standardized during scientific analysis and experiments.

Does this conversion consider any real-world factors like friction or air resistance?

No, the conversion purely changes unit of measurement. It does not affect or include physical influences like friction, air resistance, or acceleration.

How to convert back from mps to kph?

To convert meters per second back to kilometers per hour, multiply the value in mps by 3.6. This reverses the division done in kph to mps conversion.
