Unit Converters

m3/h · L/s · GPM · CFM

Quick Answer

Flow Rate Converter: m3/h · L/s · GPM · CFM. Flow Rate Converter uses standard unit conversion formulas to compute accurate results instantly.

10 m³/h =
2.77778 L/s
= 0.00277778 m³/s（SI base）

Conversion steps

  1. 1Convert to base (m³/s): 10 m³/h × 0.0002777777777777778 = 0.00277778 m³/s
  2. 2Convert to target: 0.00277778 / 0.001 = 2.77778 L/s

GPM and CFM are the dominant imperial flow units: GPM for liquids (pumps, plumbing), CFM for gases (HVAC, compressors). 1 GPM ≈ 0.227 m³/h, 1 CFM ≈ 1.699 m³/h. Mass flow (kg/h) equals volumetric flow only at water density 1000 kg/m³ — for other fluids multiply by specific gravity. In pipe sizing, water velocity is usually kept at 1-2 m/s for supply lines to balance pressure loss and noise.
