Factor1 m³/hr = 277.7778 mL/s

Converter

m³/hr

Accepts numbers or expressions, e.g. 150 + 14.7

Result
2777.78mL/s

Rendered to 6 significant figures.

Formula

Formula
mL/s = m³/hr × 277.7778

Multiply any value in cubic metres per hour by 277.7778 to obtain the value in millilitres per second.

Worked example

Convert 10 m³/hr to mL/s.

  1. 01Start with 10 m³/hr.
  2. 02Multiply by the conversion factor: 10 × 277.7778 = 2777.78 mL/s.
Result10 m³/hr = 2777.78 mL/s

FAQ

What is the conversion factor from m³/hr to mL/s?
1 m³/hr equals 277.7778 mL/s. To convert, multiply the value in cubic metres per hour by 277.7778.
How do I convert 1 m³/hr to mL/s?
1 m³/hr = 277.778 mL/s. For any value, multiply by 277.7778.
How do I convert mL/s back to m³/hr?
Divide by the same factor — or equivalently, multiply by 0.0036. So 1 mL/s = 0.0036 m³/hr.
When would I need to convert cubic metre per hour to millilitre per second?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. m³/hr to mL/s 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).
