Formula

Formula
m/day = m/s × 86400

Multiply any value in metres per second (volumetric flux) by 86400 to obtain the value in metres per day (volumetric flux).

Worked example

Convert 1 m/s to m/day.

  1. 01Start with 1 m/s.
  2. 02Multiply by the conversion factor: 1 × 86400 = 86400 m/day.
Result1 m/s = 86400 m/day

FAQ

What is the conversion factor from m/s to m/day?
1 m/s equals 86400 m/day. To convert, multiply the value in metres per second (volumetric flux) by 86400.
How do I convert 1 m/s to m/day?
1 m/s = 86400 m/day. For any value, multiply by 86400.
How do I convert m/day back to m/s?
Divide by the same factor — or equivalently, multiply by 1.157407e-5. So 1 m/day = 1.15741e-5 m/s.
When would I need to convert metre per second (volumetric flux) to metre per day (volumetric flux)?
Volumetric-flux conversions between m/s and m/day are routine in membrane filtration (RO, UF, MF, NF permeate flux), hydraulic loading specification, water-treatment design, hydrometallurgy and packed-bed column loading, and environmental engineering. LMH (L/m²/h) and gfd (gal/ft²/day) dominate membrane datasheets; m³/m²/h and m³/m²/day cover SI engineering ladders; m/day and cm/s appear as superficial velocity in hydromet and packed-bed work. Volumetric flux is the same physical quantity as superficial velocity (m³/m²/s ≡ m/s) but is kept distinct from the velocity and flow categories because the engineering intent is volumetric throughput per unit area, not bulk motion or total throughput.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
