Convert between litres/min, m³/h, and gallons/min.
Free to use, no sign-up required. Flow Rate Converter is one of 198 tools built into Xenition, alongside a chat that can use them for you.
Converts volumetric flow between litres per second, litres per minute, cubic metres per hour, and US and UK gallons per minute. Plumbers, pump buyers, and pool and irrigation owners use it to compare ratings.
Every unit is stored in litres per second. A cubic metre per hour is 1,000 l over 3,600 s, 0.2777778 L/s. US gal/min uses the 3.785 l US gallon (0.0630902 L/s) and UK gal/min the 4.546 l imperial gallon (0.0757682 L/s).
A pump rated 10 US gal/min moves 37.85412 L/min; 10 UK gal/min is 45.46092 L/min. 1 m³/h is 16.666668 L/min.
Gallons per minute, the volume it moves each minute. Check which gallon: US pumps use US gallons, while older UK kit may use imperial gallons, which are 20% bigger.
Time how long it takes to fill a bucket of known size. A 10-litre bucket filled in 20 seconds is 0.5 L/s, or 30 L/min.
Flow Rate Converter converts between 5 units: L/min, US gal/min, UK gal/min, m³/h and L/s. Factors are given against L/s.
| Unit | In L/s | 1 L/s equals |
|---|---|---|
| 1 L/min | 0.0166666667 L/s | 60 L/min |
| 1 US gal/min | 0.0630902 L/s | 15.8503222371 US gal/min |
| 1 UK gal/min | 0.0757682 L/s | 13.1981490916 UK gal/min |
| 1 m³/h | 0.2777778 L/s | 3.599999712 m³/h |
Common quantities in L/s, converted. Every value is computed from the factors above, so the chart and the converter cannot disagree.
| L/s | L/min | US gal/min | UK gal/min | m³/h |
|---|---|---|---|---|
| 1 L/s | 60 | 15.8503222371 | 13.1981490916 | 3.599999712 |
| 2 L/s | 120 | 31.7006444741 | 26.3962981831 | 7.199999424 |
| 5 L/s | 300 | 79.2516111853 | 65.9907454579 | 17.99999856 |
| 10 L/s | 600 | 158.5032223705 | 131.9814909157 | 35.99999712 |
| 25 L/s | 1500 | 396.2580559263 | 329.9537272893 | 89.9999928 |
| 100 L/s | 6000 | 1585.0322237051 | 1319.8149091571 | 359.9999712 |
1 L/s is 60 L/min. To convert L/s to L/min, divide by 0.0166666667 — so 10 L/s is 600 L/min.
1 L/min is 0.0166666667 L/s. To convert L/min to L/s, multiply by 0.0166666667 — so 10 L/min is 0.1666666667 L/s.
1 L/s is 15.8503222371 US gal/min. To convert L/s to US gal/min, divide by 0.0630902 — so 10 L/s is 158.5032223705 US gal/min.
1 US gal/min is 0.0630902 L/s. To convert US gal/min to L/s, multiply by 0.0630902 — so 10 US gal/min is 0.630902 L/s.
1 L/s is 13.1981490916 UK gal/min. To convert L/s to UK gal/min, divide by 0.0757682 — so 10 L/s is 131.9814909157 UK gal/min.
1 UK gal/min is 0.0757682 L/s. To convert UK gal/min to L/s, multiply by 0.0757682 — so 10 UK gal/min is 0.757682 L/s.
1 L/s is 3.599999712 m³/h. To convert L/s to m³/h, divide by 0.2777778 — so 10 L/s is 35.99999712 m³/h.
1 m³/h is 0.2777778 L/s. To convert m³/h to L/s, multiply by 0.2777778 — so 10 m³/h is 2.777778 L/s.
You do not have to open Flow Rate Converter to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
