GPM to m³/h
1 GPM = 0.227125 m³/h
Pump curves are where this bites: American pumps are published in GPM and everyone else's in m³/h, so comparing two candidates means converting one of them first. The factor is about 0.227, and 50 GPM landing on 11.4 m³/h is a quick sanity check. Make sure the figure is US gallons — an Imperial gallon is a fifth larger, so a British spec quoting the same number is not the same flow.

Frequently asked questions
- How many unit categories are supported?
- Over 75, from everyday units (length, mass, temperature, volume, area, speed, data storage) to technical and scientific ones (energy, pressure, torque, viscosity, molar concentration, luminance, and more).
- Does it convert engineering and scientific units?
- Yes. Alongside common units it covers engineering and scientific categories — force, pressure, torque, thermal, flow, radiology, and CSS/typography units — with precise conversion factors.
- Are the conversions accurate?
- Yes. Conversions use standard factors and precise formulas, including non-linear ones like temperature, so results are exact.
- Do I need to install an app?
- No download needed — it's a free web app that runs in any modern browser on phone, tablet, or desktop, with nothing to install and nothing sent anywhere.
