Factor1 mL/s = 0.01585032 gpm (US)

Converter

mL/s

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

Result
1.58503gpm (US)

Rendered to 6 significant figures.

Formula

Formula
gpm (US) = mL/s × 0.01585032

Multiply any value in millilitres per second by 0.01585032 to obtain the value in US gallons per minute.

Worked example

Convert 100 mL/s to gpm (US).

  1. 01Start with 100 mL/s.
  2. 02Multiply by the conversion factor: 100 × 0.01585032 = 1.58503 gpm (US).
Result100 mL/s = 1.58503 gpm (US)

FAQ

What is the conversion factor from mL/s to gpm (US)?
1 mL/s equals 0.01585032 gpm (US). To convert, multiply the value in millilitres per second by 0.01585032.
How do I convert 1 mL/s to gpm (US)?
1 mL/s = 0.0158503 gpm (US). For any value, multiply by 0.01585032.
How do I convert gpm (US) back to mL/s?
Divide by the same factor — or equivalently, multiply by 63.0902. So 1 gpm (US) = 63.0902 mL/s.
When would I need to convert millilitre per second to US gallon per minute?
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 gpm (US) 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).
