30 gallons of diesel weighs approximately 210 pounds
30 gallons of diesel fuel weighs about 210 pounds, based on the standard weight of diesel at 7 pounds per gallon. This weight can vary slightly depending on temperature and diesel grade, with colder temperatures making diesel denser and warmer temperatures making it lighter. For comparison, 30 gallons of gasoline weighs approximately 183 pounds, while 30 gallons of water weighs about 250 pounds.
Weight comparison: Diesel vs. other liquids
| Liquid | Weight per gallon | 30 gallons weight |
|---|---|---|
| Diesel fuel | 7.0 lbs | 210 lbs |
| Gasoline | 6.1 lbs | 183 lbs |
| Water | 8.34 lbs | 250 lbs |
Factors affecting diesel weight
- Temperature: Diesel expands when warm and contracts when cold, changing density by about 0.7% per 10°F
- Grade: Different diesel grades have slightly different densities
- Altitude: Higher elevations can affect fuel density slightly
Practical applications
Knowing diesel weight is important for: - Vehicle payload calculations - Fuel efficiency measurements - Transportation and shipping logistics - Fuel storage tank design
