Centimetres per Hour to Metres per Second (cm/h to m/s)
1 centimetre per hour (cm/h) = 0.000002777777778 metres per second (m/s). 1 m/s = 360000 cm/h. Example: 15 cm/h = 15 × 0.000002777777778 = 0.00004166666667 m/s.

How to Convert Centimetre per Hour to Metre per Second
- 1 cm/h = 0.000002777777778 m/s
- 1 m/s = 360000 cm/h
- Example: convert 15 cm/h to m/s: 15 cm/h = 15 × 0.000002777777778 m/s = 0.00004166666667 m/s
Formula
m/s = cm/h ÷ 360000
Derivation from SI units:
- 1 cm/h = 0.01/3600 m/s.
- Hydraulic conductivity K = discharge per unit area per unit hydraulic gradient, in m/s.
Both units are defined exactly, so the factor is exact. Centimetre per Hour definition: centimetre per hour; Metre per Second definition: metre per second.
Worked examples
- A reading of 2 cm/h converts to 0.000005555555556 m/s.
2 cm/h × 0.000002777777778 = 0.000005555555556 m/s - A value of 6.25 cm/h is 0.00001736111111 m/s.
6.25 cm/h × 0.000002777777778 = 0.00001736111111 m/s

Where it's used
Centimetres per Hour are used for infiltration capacity and Horton’s equation, while metres per second appear in darcy’s law and seepage analysis. Both measure hydraulic conductivity (coefficient of permeability k), so the conversion is a fixed factor.

Frequently asked questions
How many metres per second are in 1 centimetre per hour?
1 cm/h = 0.000002777777778 m/s.
How do I convert centimetres per hour to metres per second?
Multiply the value in cm/h by 0.000002777777778, or divide it by 360000. For example, 15 cm/h × 0.000002777777778 = 0.00004166666667 m/s.
Is the cm/h to m/s conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
