How to Convert Gallon (US)/minute to Liter/second

Converting Gallon (US)/minute (gal (US)/min) to Liter/second (L/s) is a core calculation in Volumetric Flow Rate, which quantifies the volume of fluid passing through a designated conduit cross-section per unit of time. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Gallon (US)/minute equals 0.0630902 Liter/second, while 1 L/s equals 15.850323 gal (US)/min.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (cubic meter per second (m³/s)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 gal (US)/min = 6.30902 × 10⁻⁵ cubic meter per second (m³/s)
2. Target SI Bridge (ktarget):1 L/s = 0.001 cubic meter per second (m³/s)
Step-by-step substitution for Gallon (US)/minute → Liter/second:V(L/s) = V(gal (US)/min) × ( 6.30902 × 10⁻⁵ / 0.001 ) = V(gal (US)/min) × 0.0630902
Mathematical FormulaValue in Liter/second = Value in Gallon (US)/minute × 0.063090196Direct computational formula applied for standard conversion.
Worked Example

Converting 15 gal (US)/min yields an exact output of 0.946353 L/s in Liter/second. Under higher industrial throughput, 240 gal (US)/min translates to 15.141647 L/s.

Inverse check: 1 L/s = 15.850323 gal (US)/min.

Frequently Asked Questions

There are exactly 0.063090196 liters/second (L/s) in 1 gallon (us)/minute (gal (US)/min). To calculate larger amounts manually, simply multiply your total number of gallons (us)/minute by the conversion multiplier of 0.063090196.

The mathematical formula to convert gallons (us)/minute to liters/second is: [value] * 0.063090196 = liters/second. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from liters/second back to gallons (us)/minute, you must divide your starting value by 0.063090196. Our bidirectional tool automatically computes this inverse equation the moment you type into the liter/second input field.

1 Liter/second is larger than 1 Gallon (US)/minute. Specifically, 1 Gallon (US)/minute equals 0.063090196 liters/second, meaning 1 Liter/second is 15.8503 times larger than 1 Gallon (US)/minute (a difference of 1.20 orders of magnitude). Expressing measurements in gallons (us)/minute requires a larger numerical value to represent the equivalent physical magnitude.

A typical EPA WaterSense certified residential bathroom sink faucet flow limit (1.5 gpm) measures 1.5 gpm, which corresponds to 0.09464 Liter Per Second (Liter/second).

By strict metrological definition, 1 gal (US)/min = 0.0630902 L/s.
