Convert Centimetres per Hour to Centimetres per Second
1 centimetre per hour (cm/h) = 0.0002777777778 centimetres per second (cm/s). 1 cm/s = 3600 cm/h. Example: 15 cm/h = 15 × 0.0002777777778 = 0.004166666667 cm/s.

How to Convert Centimetre per Hour to Centimetre per Second
- 1 cm/h = 0.0002777777778 cm/s
- 1 cm/s = 3600 cm/h
- Example: convert 15 cm/h to cm/s: 15 cm/h = 15 × 0.0002777777778 cm/s = 0.004166666667 cm/s
Formula
cm/s = cm/h ÷ 3600
Derivation from SI units:
- 1 cm/h = 0.01/3600 m/s.
- 1 cm/s = 0.01 m/s.
- 1 cm/h = 0.000002777777777778 m/s ÷ 0.01 m/s per cm/s = 0.0002777777777778 cm/s
Both units are defined exactly, so the factor is exact. Centimetre per Hour definition: centimetre per hour; Centimetre per Second definition: centimetre per second.
Worked examples
- A reading of 2 cm/h converts to 0.0005555555556 cm/s.
2 cm/h × 0.0002777777778 = 0.0005555555556 cm/s - A value of 6.25 cm/h is 0.001736111111 cm/s.
6.25 cm/h × 0.0002777777778 = 0.001736111111 cm/s

Where it's used
Centimetres per Hour are used for infiltration capacity and Horton’s equation, while centimetres per second appear in constant-head and falling-head permeability tests. Both measure hydraulic conductivity (coefficient of permeability k), so the conversion is a fixed factor.

Frequently asked questions
How many centimetres per second are in 1 centimetre per hour?
1 cm/h = 0.0002777777778 cm/s.
How do I convert centimetres per hour to centimetres per second?
Multiply the value in cm/h by 0.0002777777778, or divide it by 3600. For example, 15 cm/h × 0.0002777777778 = 0.004166666667 cm/s.
Is the cm/h to cm/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).
