Convert Feet per Day to Metres per Day (ft/day to m/day)
1 foot per day (ft/day) = 0.3048 metres per day (m/day). 1 m/day = 3.280839895 ft/day. Example: 50 ft/day = 50 × 0.3048 = 15.24 m/day.

How to Convert Foot per Day to Metre per Day
- 1 ft/day = 0.3048 m/day
- 1 m/day = 3.280839895 ft/day
- Example: convert 50 ft/day to m/day: 50 ft/day = 50 × 0.3048 m/day = 15.24 m/day
Formula
m/day = ft/day × 0.3048
or m/day = ft/day ÷ 3.280839895013
Derivation from SI units:
- 1 ft/day = 0.3048/86,400 m/s.
- 1 m/day = 1/86,400 m/s.
- 1 ft/day = 0.000003527777777778 m/s ÷ 0.00001157407407407 m/s per m/day = 0.3048 m/day
Both units are defined exactly, so the factor is exact. Foot per Day definition: foot per day; Metre per Day definition: metre per day.
Worked examples
- A sand aquifer of 50 ft/day is 15.24 m/day.
50 ft/day × 0.3048 = 15.24 m/day - 1 ft/day is 0.3048 m/day.
1 ft/day × 0.3048 = 0.3048 m/day
