To convert gallons of water to pounds, you use the weight of water per gallon. The weight of one gallon of water can slightly vary based on temperature, but it is typically around 8.33 to 8.345 pounds at room temperature.
For 50 gallons of water, the conversion is straightforward:
1. **Using 8.33 lb/gal**:
\[
50 \text{ gallons} \times 8.33 \text{ lb/gal} = 416.5 \text{ pounds}
\]
This is commonly used for a temperature of 68°F (20°C)[1].
2. **Using 8.3454 lb/gal**:
\[
50 \text{ gallons} \times 8.3454 \text{ lb/gal} = 417.27 \text{ pounds}
\]
This value is based on a temperature of 62°F (17°C)[2][5].
### Summary
- **At 68°F (20°C)**: 50 gallons of water weigh approximately 416.5 pounds[1].
- **At 62°F (17°C)**: 50 gallons of water weigh approximately 417.27 pounds[2][5].
Both values are very close, so depending on the precision required, you can use either for practical purposes.
