What is L/s to Cubic Foot/Hour Calculation

This calculator determines the flow rate equivalence between liters per second (L/s) and cubic feet per hour (ft³/h). The relationship is: 1 ft³/h = 0.0078657908333333 L/s. A cubic foot is approximately 28.316846592 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 127.13 ft³/h, and a flow rate of 1 ft³/h equals 0.00786579 L/s.

How to Calculate L/s and Cubic Foot/Hour

Formulas:

L/s to ft³/h: \( \text{ft}^3/\text{h} = \frac{\text{L/s}}{0.0078657908333333} \)

ft³/h to L/s: \( \text{L/s} = \text{ft}^3/\text{h} \times 0.0078657908333333 \)

Example Calculation:

• If input is 1 L/s:
• \( \text{ft}^3/\text{h} = \frac{1}{0.0078657908333333} \approx 127.13 \, \text{ft}^3/\text{h} \)
• If input is 100 ft³/h:
• \( \text{L/s} = 100 \times 0.0078657908333333 \approx 0.7866 \, \text{L/s} \)

Use the form above to input a flow rate and select the unit (L/s or ft³/h) 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.
• Cubic Feet per Hour (ft³/h): A unit representing volume flow rate, where 1 ft³/h = 0.0078657908333333 L/s.

Results are provided in both units after calculation.

FAQs

How do you calculate L/s from cubic feet/hour?

To calculate L/s from ft³/h, multiply the value in ft³/h by 0.0078657908333333. For example, 100 ft³/h × 0.0078657908333333 ≈ 0.7866 L/s.

How do you calculate cubic feet/hour from L/s?

To calculate ft³/h from L/s, divide the value in L/s by 0.0078657908333333. For example, 0.5 L/s ÷ 0.0078657908333333 ≈ 63.57 ft³/h.

What is the flow rate of 1.5 L/s in cubic feet/hour?

For 1.5 L/s: \( \text{ft}^3/\text{h} = \frac{1.5}{0.0078657908333333} \approx 190.70 \, \text{ft}^3/\text{h} \).
