Rendered to 6 significant figures.

Formula

Formula
m³/day = m³/s × 86400

Multiply any value in cubic metres per second by 86400 to obtain the value in cubic metres per day.

Worked example

Convert 1 m³/s to m³/day.

  1. 01Start with 1 m³/s.
  2. 02Multiply by the conversion factor: 1 × 86400 = 86400 m³/day.
Result1 m³/s = 86400 m³/day

FAQ

What is the conversion factor from m³/s to m³/day?
1 m³/s equals 86400 m³/day. To convert, multiply the value in cubic metres per second by 86400.
How do I convert 1 m³/s to m³/day?
1 m³/s = 86400 m³/day. For any value, multiply by 86400.
How do I convert m³/day back to m³/s?
Divide by the same factor — or equivalently, multiply by 1.157407e-5. So 1 m³/day = 1.15741e-5 m³/s.
When would I need to convert cubic metre per second to cubic metre per day?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. m³/s to m³/day is a frequently needed conversion for flow datasheet preparation.
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).
