Density (lb/gal):

What is g/cm³ to lb/gal Conversion

g/cm³ to lb/gal conversion is a unit transformation for density, converting grams per cubic centimeter (g/cm³) to pounds per gallon (lb/gal), using the US gallon as the standard volume unit. This conversion is useful in industries like manufacturing and chemistry, bridging metric and imperial systems. The conversion factor is derived from the relationships between grams and pounds (1 g = 0.00220462 lb) and cubic centimeters and US gallons (1 gal = 3785.41 cm³), resulting in \(1 \, \text{g/cm³} \approx 8.3454 \, \text{lb/gal}\).

For example, a density of 1 g/cm³ converts to 8.3454 lb/gal.

How to Convert g/cm³ to lb/gal

Conversion Formula: The density in lb/gal is calculated as:

\(\rho_{\text{lb/gal}} = \rho_{\text{g/cm³}} \times 8.3454\)

Where:

\(\rho_{\text{lb/gal}}\) = Density in pounds per US gallon
\(\rho_{\text{g/cm³}}\) = Density in grams per cubic centimeter

Example Calculation: For a density of 1.5 g/cm³:

\(\rho_{\text{lb/gal}} = 1.5 \times 8.3454 \approx 12.5181 \, \text{lb/gal}\).

Use the form above to input the density in g/cm³, and the calculator will convert it to lb/gal.

Density Units and Conversions

The calculator converts between the following density units:

Grams per cubic centimeter (g/cm³): Base input unit
Pounds per US gallon (lb/gal): 1 g/cm³ ≈ 8.3454 lb/gal

Other common conversions include:

1 g/cm³ = 1000 kg/m³
1 g/cm³ = 1 kg/L
1 lb/gal ≈ 119.826 kg/m³

Note: This calculator uses the US gallon (1 gal = 3785.41 cm³). The UK (Imperial) gallon (1 gal = 4546.09 cm³) would yield a different factor (≈ 10.0224 lb/gal).

Standard Density Examples

Some standard densities include:

Water at 4 °C: \(\rho \approx 1.0000 \, \text{g/cm³} \approx 8.3454 \, \text{lb/gal}\)
Gold: \(\rho \approx 19.3200 \, \text{g/cm³} \approx 161.28 \, \text{lb/gal}\)
Air at sea level: \(\rho \approx 0.001225 \, \text{g/cm³} \approx 0.0102 \, \text{lb/gal}\)

FAQs

How do you convert g/cm³ to lb/gal?

To convert g/cm³ to lb/gal:

Take the density value in g/cm³.
Multiply by 8.3454 (since \(1 \, \text{g/cm³} \approx 8.3454 \, \text{lb/gal}\), based on 1 gal = 3785.41 cm³ and 1 g = 0.00220462 lb).

What is the density of water in lb/gal if it is 1 g/cm³?

The density is \(1 \times 8.3454 \approx 8.3454 \, \text{lb/gal}\).
