Depends on what you are measuring. If it was water, the weight would be 1 ton, or 2,000 pounds.
500 gallons of pure water weigh 4,172.6 pounds (rounded) With 250 pounds of salt added, the mixture had better weigh 4,172.6 + 250 = 4,422.6 pounds, or else mass has disappeared, which is a no-no.
250 liters is 66.043 US gallons.
About 1,538 pounds for 250 gallons.
Weight: 210-250 k
1 gallon of oil to 250 gallons of gas is 1.953125 ounces per gallon; you would need 39.0625 ounces of oil for 20 gallons of gas.
250 US gallons = 946 L250 UK gallons = 1,140 L
250 fluid ounces is 1.95 gallons.
250 US gallons is 33.4201 cubic feet.
That depends on the type material you are referring to. Also, these are two different types of measurements. Gallons is a measure of volume but the other is weight or mass. Please edit your question to include more context or details.
250 Microgram approx
9,530 gallons of plain water weighs 79,527.85 pounds or 39.76 tons.
Assuming you wanted to preserve the ratio of product-to-water, we solve this by setting up and solving the equation: 1/50000 = x/250 From this, just multiply both sides by 250, yielding x = 250/50000 = 1/200. So you would add 1/200 = 0.005 gallons of product to 250 gallons of water.
