About

In physics and engineering, the SI derived unit for volume is the cubic meter (m³). While liters are convenient for everyday fluids, equations regarding flow rate, density, or thermodynamics usually require input in cubic meters. The conversion factor is 1000, meaning 1 cubic meter contains 1000 liters.

This tool is optimized for scientific workflows. It offers a "Scientific Mode" to format results in standard index form (e.g., 1.5e-3), facilitating direct transcription into calculation software or academic papers.

Formulas

The relationship between the Liter and the Cubic Meter is a factor of 1000 ($10^3$).

V_m³ = V_L1000

Or expressed in powers of ten:

1 L = 10^-3 m³

Reference Data

Frequently Asked Questions

Imagine a cube 10cm x 10cm x 10cm; that is one Liter. Now imagine a box 1m x 1m x 1m; that is one Cubic Meter. It takes exactly 1,000 of the small liter cubes to fill the large cubic meter box.

Scientific notation is best when dealing with very small volumes (e.g., microliters converted to m³) or when inputting data into engineering software like MATLAB or Python, which often prefer "e" notation (e.g., 5.2e-4).

Only for pure water at standard temperature. 1 Cubic Meter of water has a mass of approx 1 Tonne (1000 kg). For other substances, density determines the mass.
