Feet per Day to Centimetres per Second (ft/day to cm/s)
1 foot per day (ft/day) = 0.0003527777778 centimetres per second (cm/s). 1 cm/s = 2834.645669 ft/day. Example: 15 ft/day = 15 × 0.0003527777778 = 0.005291666667 cm/s.

How to Convert Foot per Day to Centimetre per Second
- 1 ft/day = 0.0003527777778 cm/s
- 1 cm/s = 2834.645669 ft/day
- Example: convert 15 ft/day to cm/s: 15 ft/day = 15 × 0.0003527777778 cm/s = 0.005291666667 cm/s
Formula
cm/s = ft/day × 0.0003527777777778
or cm/s = ft/day ÷ 2834.645669291
Derivation from SI units:
- 1 ft/day = 0.3048/86,400 m/s.
- 1 cm/s = 0.01 m/s.
- 1 ft/day = 0.000003527777777778 m/s ÷ 0.01 m/s per cm/s = 0.0003527777777778 cm/s
Both units are defined exactly, so the factor is exact. Foot per Day definition: foot per day; Centimetre per Second definition: centimetre per second.
Worked examples
- A reading of 3 ft/day converts to 0.001058333333 cm/s.
3 ft/day × 0.0003527777778 = 0.001058333333 cm/s - A value of 50 ft/day is 0.01763888889 cm/s.
50 ft/day × 0.0003527777778 = 0.01763888889 cm/s

Where it's used
Feet per Day are used for USGS aquifer reports, 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 foot per day?
1 ft/day = 0.0003527777778 cm/s.
How do I convert feet per day to centimetres per second?
Multiply the value in ft/day by 0.0003527777778, or divide it by 2834.645669. For example, 15 ft/day × 0.0003527777778 = 0.005291666667 cm/s.
Is the ft/day 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).
