About Converting Centimeter per Hours to m/s
Centimeter per Hours and m/s both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Specifically: Distance divided by time, and meters per second.
Formula
m/s = centimeter per hours × 0.00000277777777778
This factor comes from each unit's defined relationship to the category's base unit: 1 centimeter per hours equals 0.00000277777777778 base units, and 1 m/s equals 1 base unit, so dividing one by the other gives the direct centimeter per hours-to-m/s factor of 0.00000277777777778.
Simple example
1 cm/h × 0.000002777777778 = 0.0000027778 m/s
1 centimeter per hours = 0.0000027778 m/s.
Real-world example
10 cm/h × 0.000002777777778 = 0.0000277778 m/s
10 centimeter per hours = 0.0000277778 m/s.

Reverse conversion: m/s to Centimeter per Hours
0.0000027778 m/s × 360000 = 1.000008 cm/h
0.0000027778 m/s = 1.000008 centimeter per hours.
centimeter per hours = m/s × 360000

Understanding the Centimeter per Hours (cm/h)
Distance divided by time.
Understanding the m/s
m/s (m/s) measures speed. The meter per second is the SI derived unit of speed: one meter of distance per second of time. It is classified as a SI derived unit.
Where it's used: Standard scientific speed unit worldwide
Uses of the m/s today
- Scientific and engineering speed/velocity calculations
- Meteorology (wind speed, alongside km/h and knots)
- Physics education and calculations
History of the m/s
As a coherent SI derived unit, meters per second follows automatically from the meter and second, the SI base units of length and time, without an independent historical origin.
Historical origin. m/s was not the invention of a single named person; it developed through the process described above.
m/s — sources
- BIPM SI Brochure — Coherent derived units — Defines m/s as the SI unit of speed.

Frequently asked questions
How many m/s are in 1 centimeter per hours?
1 centimeter per hours equals 0.0000027778 m/s, using the exact defined conversion factor rather than an estimate.
How do I convert centimeter per hours to m/s?
Multiply the centimeter per hours value by 0.000002777777778. The converter above does this instantly to whatever precision you set.
How do I convert m/s back to centimeter per hours?
Use the reverse factor: 1 m/s equals 360,000 centimeter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a centimeter per hours?
Centimeter per Hours (cm/h) is a unit of speed.
What is a m/s?
m/s (m/s) measures speed. The meter per second is the SI derived unit of speed: one meter of distance per second of time. It is classified as a SI derived unit.
Is the centimeter per hours to m/s conversion exact?
Yes. Both centimeter per hours and m/s are defined by fixed standards rather than physical artifacts, so the factor of 0.000002777777778 used above is exact to as many digits as you choose to display.
