Formula

input_flow ÷ from_factor × to_factor

Converts via SI base (m³/s): result = value × (factor_from / factor_to). Factors are units per m³/s: m³/s=1, m³/h=3600, L/min=60000, L/s=1000, GPM=15850.

Introduction

Convert between common volumetric flow rate units used in engineering: cubic meters per hour/second, liters per minute/second, and US gallons per minute.

Calculation Example

100 m³/h = 440.3 GPM (US gallons per minute).

Inputs: input_flow=100, from_factor=3600, to_factor=15850

Result: 440.3

Engineering Applications

•Unit conversion

Frequently Asked Questions

What is the conversion from m³/h to GPM?

1 m³/h = 4.403 US GPM. 1 m³/h = 3.666 UK (imperial) GPM.

How do I convert mass flow to volumetric flow?

Volumetric flow (m³/s) = mass flow (kg/s) / density (kg/m³). For water, 1 kg/s ≈ 3.6 m³/h.
