Water Weight Formula:
From: | To: |
The gallons to pounds conversion calculates the weight of water based on its volume. Since water has a known density, we can accurately convert between volume and weight measurements.
The calculator uses the simple formula:
Where:
Explanation: This conversion factor accounts for the density of water at room temperature (approximately 62.4 lb/ft³).
Details: Knowing the weight of water is essential for engineering calculations, shipping and transportation, tank design, and various industrial applications where water volume needs to be converted to weight.
Tips: Enter volume in gallons (must be a positive number). The calculator will automatically compute the equivalent weight in pounds.
Q1: Why is the conversion factor 8.34?
A: This comes from the density of water (62.4 lb/ft³) divided by 7.48052 gallons per cubic foot.
Q2: Does temperature affect the conversion?
A: Slightly. Water density changes with temperature, but 8.34 is standard for room temperature (about 20°C or 68°F).
Q3: Can this be used for other liquids?
A: No, this is specific to water. Other liquids have different densities and thus different conversion factors.
Q4: How precise is this conversion?
A: Very precise for most practical purposes. The density of pure water at standard conditions is well-defined.
Q5: What about saltwater?
A: Saltwater is denser (about 8.6 lb/gal). Use a different factor for seawater calculations.
