About

Converting liters to kilograms requires knowledge of the substance's density or Specific Gravity (SG). While water has a convenient 1:1 ratio (approximate), industrial chemicals vary wildly. Sulfuric acid is nearly twice as heavy as water per unit volume, while solvents like acetone are significantly lighter.

This tool is designed for laboratory and industrial applications where mass balance calculations are critical. It allows for the selection of common reagents from a verified database or manual input of Specific Gravity for proprietary mixtures.

Formulas

The conversion relies on the definition of density ($ρ$) as mass per unit volume. Since 1 Liter is 0.001 cubic meters and density is often given in kg/L (equivalent to Specific Gravity relative to water), the calculation is linear.

m = V × ρ

Where:

m = Mass in kilograms (kg)
V = Volume in liters (L)
ρ = Density in kg/L (or Specific Gravity)

Frequently Asked Questions

Liquids expand when heated, increasing their volume while mass remains constant. This decreases density. The specific gravities listed here are standard values (typically at 20°C or 25°C). For high-precision chemical engineering, temperature correction factors must be applied.

Yes, for practical purposes in the metric system. Specific Gravity is the ratio of a substance's density to the density of water. Since water is approximately 1 kg/L, the SG value is numerically equal to density in kg/L.

Data is aggregated from standard chemical safety data sheets (SDS) and PubChem values at standard ambient temperature and pressure (SATP).
