1 cubic mile = 1.10111715 × 1012 US gallons.
The United States Geologic Survey (USGS) estimates there to be 326,000,000 cubic miles of water on the planet. A cubic mile can hold a little more than 1.1 X 1012 gallons. The USGS also estimates that 96.5% of that water is in the planets oceans. 96.5% X (1,100,000,000,000 gallons per cubic mile) X (326,000,000 cubic miles) =============================== = 346,049,000,000,000,000,000 gallons.
Water volume of 35.2 km3 (28,500,000 acre·ft)----- 28.5 million acre-feet x 43,560 square feet in an acre = 1.24 trillion cubic feet x 8.1 (gallons in a cubic foot) = 10 trillion gallons
17.8 gallons.
1 inch * 1 acre = 102.790153 m3 1 US gallon = 0.00378541178 cubic meter 102.790153/0.00378541178= 27 154.2849 So 27 154 gallons
One square foot is 144 square inches, so if you cover that with an inch of water you'll need 144 cubic inches. One gallon is 231 cubic inches. Dividing 231 by 144 = 0.62 gallons. So a plant growing in about 1 square foot of soil needs a bit more than half a gallon of water a week to equal 1 inch. A 4 ft x 8 ft bed = 32 sq. ft. so at 0.62 gal/sq.ft. you'd want to give it about 20 gallons of water a week.
A 15 cubic foot tank will hold a maximum of about 112.2 gallons of water.
452 cubic feet will contain a maximum of 3,381.2 US gallons of water.
This aquarium can hold a maximum of 10 gallons of water.
0.1912 gallons.
240 cubic feet equates to a volume of 1,795.32 gallons.
The pipe can hold up to 6,762.39 US gallons of water.
A pool with a volume of 43,308 cubic feet can hold up to about 323,966 US gallons of water!
A pipe with a volume of 44.17 cubic inches holds up to: 0.1912 US gallons of water.
1 cubic foot = 7.48051948 US Gallons = 6.22883288 Imperial Gallons Therefore, 1000 cubic feet = 7480.51948 US Gallons = 6228.83288 Imperial Gallons
One cubic foot of water is 7.4805 gallons.
96 cubic feet will hold a little over 718 gallons
75 divided by 7.48 gallons per cu ft = about 10 cubic feet
