Centimetres per Second to Metres per Day (cm/s to m/day)
1 centimetre per second (cm/s) = 864 metres per day (m/day). 1 m/day = 0.001157407407 cm/s. Example: 0.001 cm/s = 0.001 × 864 = 0.864 m/day.
Also searched as cm/s to m/day, cm/sec to m/d, permeability cm/s to m per day and coefficient of permeability conversion.
1 cm/s = 864 m/day

How to Convert Centimetre per Second to Metre per Day
- 1 cm/s = 864 m/day
- 1 m/day = 0.001157407407 cm/s
- Example: convert 0.001 cm/s to m/day: 0.001 cm/s = 0.001 × 864 m/day = 0.864 m/day
Formula
m/day = cm/s × 864
Derivation from SI units:
- 1 cm/s = 0.01 m/s.
- 1 m/day = 1/86,400 m/s.
- 1 cm/s = 0.01 m/s ÷ 0.00001157407407407 m/s per m/day = 864 m/day
Both units are defined exactly, so the factor is exact. Centimetre per Second definition: centimetre per second; Metre per Day definition: metre per day.
Worked examples
- A fine sand with k = 0.001 cm/s conducts 0.864 m/day.
0.001 cm/s × 864 = 0.864 m/day - A coarse sand of 0.1 cm/s is 86.4 m/day.
0.1 cm/s × 864 = 86.4 m/day

Where it's used
Laboratory permeability results in cm/s, from constant-head and falling-head tests, are converted to m/day for groundwater, well and drainage calculations. Multiply by 864.

Frequently asked questions
How many m/day is 1 cm/s?
Exactly 864 m/day: 0.01 m/s × 86,400 s/day. So 10⁻³ cm/s = 0.864 m/day.
Is k in cm/s the same as hydraulic conductivity?
Yes. The “coefficient of permeability” k of soil mechanics is the hydraulic conductivity K of hydrology, for water at the test temperature.
How many metres per day are in 1 centimetre per second?
1 cm/s = 864 m/day.
How do I convert centimetres per second to metres per day?
Multiply the value in cm/s by 864. For example, 0.001 cm/s × 864 = 0.864 m/day.
Is the cm/s to m/day 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).
