This calculator determines the flow rate equivalence between liters per second (L/s) and cubic millimeters per second (mm³/s). The relationship is: 1 mm³/s = 0.000001 L/s (1.0E-6 L/s). This reflects the fact that 1 liter equals 1,000,000 cubic millimeters (1 L = 10⁶ mm³), with the time base (seconds) unchanged.
For example, a flow rate of 1 L/s is equivalent to 1,000,000 mm³/s, and a flow rate of 500,000 mm³/s is equivalent to 0.5 L/s.
Formulas:
L/s to mm³/s: \( \text{mm}^3/\text{s} = \text{L/s} \times 10^6 \)
mm³/s to L/s: \( \text{L/s} = \frac{\text{mm}^3/\text{s}}{10^6} \)
Example Calculation:
Use the form above to input a flow rate and select the unit (L/s or mm³/s) to calculate the equivalent value in the other unit.
The following table provides examples of calculated values between L/s and mm³/s:
| L/s | mm³/s |
|---|---|
| 0.000001 | 1 |
| 0.5 | 500000 |
| 1 | 1000000 |
| 10 | 10000000 |
The calculator uses the following units:
Results are provided in both units after calculation.
How do you calculate L/s from cubic millimeters/second?
To calculate L/s from mm³/s, divide the value in mm³/s by 1,000,000. For example, 500,000 mm³/s ÷ 10⁶ = 0.5 L/s.
How do you calculate cubic millimeters/second from L/s?
To calculate mm³/s from L/s, multiply the value in L/s by 1,000,000. For example, 1 L/s × 10⁶ = 1,000,000 mm³/s.
What is the flow rate of 2 L/s in cubic millimeters/second?
For 2 L/s: \( \text{mm}^3/\text{s} = 2 \times 10^6 = 2000000 \, \text{mm}^3/\text{s} \).
