This calculator determines the flow rate equivalence between liters per second (L/s) and thousand cubic feet per hour (kft³/h). The relationship is: 1 kft³/h = 7.8657908333333 L/s. Here, "kft³" represents 1,000 cubic feet, a volume unit converted to liters and divided by 3,600 seconds per hour.
For example, a flow rate of 7.8657908333333 L/s equals 1 kft³/h, and a flow rate of 1 L/s equals approximately 0.1271 kft³/h.
Formulas:
L/s to kft³/h: \( \text{kft}^3/\text{h} = \frac{\text{L/s}}{7.8657908333333} \)
kft³/h to L/s: \( \text{L/s} = \text{kft}^3/\text{h} \times 7.8657908333333 \)
Example Calculation:
Use the form above to input a flow rate and select the unit (L/s or kft³/h) to calculate the equivalent value in the other unit.
The following table provides examples of calculated values between L/s and kft³/h:
| L/s | kft³/h |
|---|---|
| 7.8658 | 1 |
| 1 | 0.1271 |
| 15.7316 | 2 |
| 3.9329 | 0.5 |
The calculator uses the following units:
Results are provided in both units after calculation.
How do you calculate L/s from thousand cubic feet/hour?
To calculate L/s from kft³/h, multiply the value in kft³/h by 7.8657908333333. For example, 2 kft³/h × 7.8657908333333 = 15.731581666667 L/s.
How do you calculate thousand cubic feet/hour from L/s?
To calculate kft³/h from L/s, divide the value in L/s by 7.8657908333333. For example, 3.9329 L/s ÷ 7.8657908333333 ≈ 0.5 kft³/h.
What is the flow rate of 10 L/s in thousand cubic feet/hour?
For 10 L/s: \( \text{kft}^3/\text{h} = \frac{10}{7.8657908333333} \approx 1.2713 \, \text{kft}^3/\text{h} \).
