If you have a fresh water tank 30 gal * 8.33 = 250 lbs
Salt water is slightly heavier (about a 1/4 pound per gallon)
30 * 8.55 = 256.5 lbs

A gallon of fresh water weighs 7-1/2 pounds. Multiply that by 30.

A gallon of water is about 8 pounds, so the water will be about 240-250 pounds. By the time you add the tank and any gravel, the whole unit will be close to 275 pounds.

If it's a US gallon then 30 x 8.3 = 249 lbs.
If it's a UK gallon then 30 x 10 = 300 lbs.

First you have to know if it is US Gallons or Imperial (British) Gallons. A US Gallon is 3.785 Liters/Gallon while an Imperial Gallon is 4.54 Liters.
One liter of WATER weight One kilogram (other liquids weigh more or less depending on specific gravity, but as it is a fishtank and I am assuming water for the fish 1-1 for water is probably right).
So 30 US Gal x 3.785L/Gal x 1kg/L = 113.5Kg (250lb)
Or 30 Imp Gal x 4.54L/Gal x 1kg/L = 136Kg (300lb)
Hope that helps

1 Gallon of water weights approx. 8.1 lbs.
But if your designing a stand for this, you would be better off to design based on 1gallon=16 lbs or a factor of safety of 2.

a gallon takes 8.3389 pounds of distilled water (3.7853 liters). so 30 gallons is 250.2 pounds there or there bouts, or 113.6liters

A gallon of water weighs 8.34 pounds,more if it's salt water.So 30x8.34=241 pounds roughly.

30 (US) gallons=113.562 L=113562 cm3 =0.113562 m3
1 m3 water =1000kg (Density of water = 1000 kg/m3)
0.113562 m3 water = 113.562 kg
(1 kg=2.2046226218488 pounds)
Answer: approx 114 kg or 250 pounds

Depends if you are talking US gallons or Imperial gallons. 10lbs for an Imperial gallon and 8lbs for a US gallon.
