Volumetric Flow Rate

mL/stoL/hr

Convert millilitres per second (mL/s) to litres per hour (L/hr).

Factor1 mL/s = 3.6 L/hr

Converter

mL/s

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

Result
3.6L/hr

Rendered to 6 significant figures.

Formula

Formula
L/hr = mL/s × 3.6

Multiply any value in millilitres per second by 3.6 to obtain the value in litres per hour.

Worked example

Convert 1 mL/s to L/hr.

  1. 01Start with 1 mL/s.
  2. 02Multiply by the conversion factor: 1 × 3.6 = 3.6 L/hr.
Result1 mL/s = 3.6 L/hr

FAQ

What is the conversion factor from mL/s to L/hr?
1 mL/s equals 3.6 L/hr. To convert, multiply the value in millilitres per second by 3.6.
How do I convert 1 mL/s to L/hr?
1 mL/s = 3.6 L/hr. For any value, multiply by 3.6.
How do I convert L/hr back to mL/s?
Divide by the same factor — or equivalently, multiply by 0.2777778. So 1 L/hr = 0.277778 mL/s.
When would I need to convert millilitre per second to litre per hour?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. mL/s to L/hr 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).
