Convert Metres per Day to Metres per Second (m/day to m/s)
1 metre per day (m/day) = 0.00001157407407 metres per second (m/s). 1 m/s = 86400 m/day. Example: 15 m/day = 15 × 0.00001157407407 = 0.0001736111111 m/s.

How to Convert Metre per Day to Metre per Second
- 1 m/day = 0.00001157407407 m/s
- 1 m/s = 86400 m/day
- Example: convert 15 m/day to m/s: 15 m/day = 15 × 0.00001157407407 m/s = 0.0001736111111 m/s
Formula
m/s = m/day × 0.00001157407407407
or m/s = m/day ÷ 86400
Derivation from SI units:
- 1 m/day = 1/86,400 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. Metre per Day definition: metre per day; Metre per Second definition: metre per second.
Worked examples
- A reading of 0.5 m/day converts to 0.000005787037037 m/s.
0.5 m/day × 0.00001157407407 = 0.000005787037037 m/s - A value of 10 m/day is 0.0001157407407 m/s.
10 m/day × 0.00001157407407 = 0.0001157407407 m/s

Where it's used
Metres per Day are used for aquifer transmissivity T = K b (m²/day), 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 metre per day?
1 m/day = 0.00001157407407 m/s.
How do I convert metres per day to metres per second?
Multiply the value in m/day by 0.00001157407407, or divide it by 86400. For example, 15 m/day × 0.00001157407407 = 0.0001736111111 m/s.
Is the m/day 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).
