About the Density Converter

Density Converter is treated here as a quantitative relation between Density Value and From Unit and g/cm^3, kg/m^3, lb/ft^3 and lb/gal.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
Base unit: g/cm^3 (= g/mL = kg/L)
1 g/cm^3 = 1,000 kg/m^3 = 62.428 lb/ft^3 = 8.345 lb/gal
Specific gravity = density / 0.9982 g/cm^3 (water at 20 degC)

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

Base unit: g/cm^3 (= g/mL = kg/L)
1 g/cm^3 = 1,000 kg/m^3 = 62.428 lb/ft^3 = 8.345 lb/gal
Specific gravity = density / 0.9982 g/cm^3 (water at 20 degC)

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Water: 1.000 g/cm³

Inputs

value: 1 from_unit: g/cm³ (g/mL)
g/cm^3: 1.73 g/cm^3. kg/m^3: 1,730 kg/m^3. lb/ft^3: 108.003 lb/ft^3. lb/gal: 14.4376 lb/gal. Specific Gravity: 1.7331

With Density Value = 1 and From Unit = g/cm^3 (g/mL) as the stated inputs, the result is g/cm^3 = 1.73 g/cm^3, kg/m^3 = 1,730 kg/m^3 and lb/ft^3 = 108.003 lb/ft^3. Each value corresponds to the declared output fields.

Example 2: Steel: 7.85 g/cm³

Inputs

value: 7.85 from_unit: g/cm³ (g/mL)
g/cm^3: 13.5805 g/cm^3. kg/m^3: 13,580.5 kg/m^3. lb/ft^3: 847.827 lb/ft^3. lb/gal: 113.3352 lb/gal. Specific Gravity: 13.605

With Density Value = 7.85 and From Unit = g/cm^3 (g/mL) as the stated inputs, the result is g/cm^3 = 13.5805 g/cm^3, kg/m^3 = 13,580.5 kg/m^3 and lb/ft^3 = 847.827 lb/ft^3. Each value corresponds to the declared output fields.

Example 3: Diesel Fuel: 0.85 g/cm³

Inputs

value: 0.85 from_unit: g/cm³ (g/mL)
g/cm^3: 1.4705 g/cm^3. kg/m^3: 1,470.5 kg/m^3. lb/ft^3: 91.803 lb/ft^3. lb/gal: 12.272 lb/gal. Specific Gravity: 1.4732

With Density Value = 0.85 and From Unit = g/cm^3 (g/mL) as the stated inputs, the result is g/cm^3 = 1.4705 g/cm^3, kg/m^3 = 1,470.5 kg/m^3 and lb/ft^3 = 91.803 lb/ft^3. Each value corresponds to the declared output fields.

Example 4: Concrete: 2.3 g/cm³

Inputs

value: 2.3 from_unit: g/cm³ (g/mL)
g/cm^3: 3.979 g/cm^3. kg/m^3: 3,979 kg/m^3. lb/ft^3: 248.408 lb/ft^3. lb/gal: 33.2065 lb/gal. Specific Gravity: 3.9862

With Density Value = 2.3 and From Unit = g/cm^3 (g/mL) as the stated inputs, the result is g/cm^3 = 3.979 g/cm^3, kg/m^3 = 3,979 kg/m^3 and lb/ft^3 = 248.408 lb/ft^3. Each value corresponds to the declared output fields.
