LPM إلى GPM

LPM to GPM Conversion

LPM to GPM converts litres per minute into US gallons per minute. The standard factor is 1 LPM = 0.264172 US GPM. Use the calculator above to get instant lpm gpm results for any value. The conversion works for water, fuel, hydraulic fluid, and any liquid measured in the same unit system.

Converting lpm into gpm is essential when metric pump data must match US specifications. Most US pump curves, pressure-washer ratings, plumbing codes, and irrigation controllers publish flow in GPM. The lpm to gpm us factor (0.264172) uses the US liquid gallon (3.785411784 litres), not the Imperial gallon.

Example: 25 LPM × 0.264172 = 6.604 GPM  |  LPM to gallons per minute using the US standard.

How to Convert LPM to GPM

To convert LPM to GPM, multiply the LPM value by 0.264172. This single step is the complete lpm to gpm conversion. There is no rounding required for most engineering checks — simply multiply and retain 3 decimal places.

To lpm convert to gpm in reverse, multiply GPM by 3.785411784. This conversion lpm to gpm formula is exact because both the US gallon and the litre are defined in SI units. No temperature or pressure correction is needed for volumetric liquid flow at standard conditions.

For a quick l min to gpm conversion, enter any value in the calculator above and the result updates instantly. The formula is identical whether you write the unit as LPM, L/min, or litres per minute.

Convert LPM to GPM: 100 LPM × 0.264172 = 26.417 US GPM

Liters Per Minute to Gallons Per Minute

Liters per minute to GPM and litres per minute to gallons per minute refer to the same conversion — only the spelling differs between American English (liters) and British English (litres). Both use the same factor: multiply by 0.264172 for US GPM.

To convert liters per minute to GPM, use the formula GPM = L/min × 0.264172. To convert liters per minute to gallons per minute in reverse, multiply GPM by 3.785411784. The same formula applies whether you write it as liters/min to gpm, liters per min to gpm, or litres per min to gpm.

For bulk conversions, note that liters min to gallons min describes the same quantity. The unit notation may vary across datasheets — L/min, lpm, l/min, and litres per minute all mean the same thing. When you need to convert liters per min to gpm, always confirm whether the GPM target is US or Imperial before applying the factor.

The term liters to gpm is also used informally when the per-minute time base is understood from context, such as in pump sizing where flow rate is always per minute.

Liters per minute to gallons per minute: 50 L/min × 0.264172 = 13.209 US GPM

L Min to GPM — All Notations

L/min to GPM, l min to gpm, l per min to gpm, and l/m to gpm all describe the same conversion. The forward slash notation (L/min) is the SI-preferred form, while the space notation (l min) appears on older instruments and datasheets. All produce the same result: multiply by 0.264172 for US GPM.

The notation l min to gal min (litres per minute to gallons per minute) is a shorthand used in spreadsheets and conversion tables. L to gpm is sometimes used informally when the per-minute base rate is understood. In every case the conversion factor is the same.

For a quick l min to gpm conversion, just enter the L/min value into the calculator above. The result is the same whether your instrument displays the unit as L/min, l/min, or lpm.

L/min to GPM: 200 L/min × 0.264172 = 52.834 US GPM

Liter to GPM Conversion

Liter per minute to GPM, liter/min to gpm, liter min to gpm, and liter per min to gpm are the singular-form equivalents of the liters per minute expressions. Technically, flow rate is always expressed in the plural for values above 1, but search queries and instrument labels frequently use the singular form. The conversion is identical: multiply by 0.264172.

To convert liter per minute to GPM, use: GPM = liter/min × 0.264172. The term liter to gpm is also used informally for quick comparisons between metric and US flow data. A 1 liter per minute flow equals 0.264 GPM; a 10 liter per minute flow equals 2.642 GPM.

Liter per minute to GPM: 1 liter/min = 0.264 GPM  |  10 liter/min = 2.642 GPM
