What is L/s to Gallon/Hour (US) Calculation

This calculator determines the flow rate equivalence between liters per second (L/s) and US gallons per hour (gal/h). The relationship is: 1 gal/h (US) = 0.0010515032777778 L/s. A US gallon is 3.785411784 liters, and this volume delivered over an hour (3,600 seconds) results in a small flow rate in L/s.

For example, a flow rate of 1 L/s equals approximately 951 gal/h, and a flow rate of 1 gal/h equals 0.0010515 L/s.

How to Calculate L/s and Gallon/Hour (US)

Formulas:

L/s to gal/h (US): \( \text{gal/h} = \frac{\text{L/s}}{0.0010515032777778} \)

gal/h (US) to L/s: \( \text{L/s} = \text{gal/h} \times 0.0010515032777778 \)

Example Calculation:

• If input is 1 L/s:
• \( \text{gal/h} = \frac{1}{0.0010515032777778} \approx 951.00 \, \text{gal/h} \)
• If input is 1000 gal/h:
• \( \text{L/s} = 1000 \times 0.0010515032777778 \approx 1.0515 \, \text{L/s} \)

Use the form above to input a flow rate and select the unit (L/s or gal/h [US]) to calculate the equivalent value in the other unit.

Flow Rate Units

The calculator uses the following units:

• Liters per Second (L/s): A standard unit for measuring flow rate in fluid dynamics.
• Gallons per Hour (US) (gal/h): A unit representing US gallons per hour, where 1 gal/h (US) = 0.0010515032777778 L/s.

Results are provided in both units after calculation.

FAQs

How do you calculate L/s from gallons/hour (US)?

To calculate L/s from gal/h (US), multiply the value in gal/h by 0.0010515032777778. For example, 1000 gal/h × 0.0010515032777778 ≈ 1.0515 L/s.

How do you calculate gallons/hour (US) from L/s?

To calculate gal/h (US) from L/s, divide the value in L/s by 0.0010515032777778. For example, 0.5 L/s ÷ 0.0010515032777778 ≈ 475.50 gal/h.

What is the flow rate of 2 L/s in gallons/hour (US)?

For 2 L/s: \( \text{gal/h} = \frac{2}{0.0010515032777778} \approx 1902.00 \, \text{gal/h} \).
