# lb to US gal – pounds to US gallons – mass to volume online

Mass (weight) in pounds (lb):

Density in

Volume in US gallons (US gal):

0.00US gal

Density of some materials:

• Air ≈ 0.01 lb/(US gal)
• Aluminum = 22.53 lb/(US gal)
• Concrete ≈ 20.03 lb/(US gal)
• Diesel ≈ 7.09 lb/(US gal),
• Gasoline (petrol) ≈ 5.93 lb/(US gal)
• Steel = 65.51 lb/(US gal)
• Water (4°C) = 8.345 lb/(US gal)

## How to convert from lb to US gal?

The volume in US gallons is equal to the mass (weight) in pounds divided by the density in pounds per US gallon.

Formula:

V = m / p

V – volume in US gallons (US gal);

m – mass (weight) in pounds (lb);

ρ – density in pounds per US gallon (lb/(US gal)).

Example

Convert 100 lb to US gal if the density is 8.345 lb/(US gal).

Solution: V = m / p = 100 / 8.345 = 11.98 US gal. Answer: 100 lb = 11.98 gal (density = 8.345 lb/US gal)
