Conversion Formulas

Gallons into Pounds: Multiply the specific gravity of the liquid by 8.33* (weight in pounds of 1 gallon of water); then multiply this result by the number of gallons, to obtain the weight in pounds.

Pounds into Gallons: Multiply the specific gravity of the liquid by 8.33* (weight in pounds of 1 gallon of water); then divide the number of pounds by the result, to obtain the volume in gallons.

Milliliters into Grams: Multiply the specific gravity of the substance by the number of milliliters, to obtain the weight in grams.

Grams into Milliliters: Divide the number of grams by the specific gravity of the substance, to obtain the volume in milliliters.

Milliliters into Pounds: Multiply the number of milliliters by the specific gravity of the substance; then divide the product by 453.59 (equivalent in grams of 1 avoirdupois pound), to obtain the weight in pounds.

Pounds into Milliliters: Multiply the number of pounds by 453.59 (equivalent in grams of 1 avoirdupois pound); then divide the product by the specific gravity of the substance, to obtain the volume in milliliters.

Milliliters into Ounces: Multiply the number of milliliters by the specific gravity of the substance; then divide the product by 28.35 (equivalent in grams of 1 avoirdupois ounce), to obtain the volume in ounces.

Ounces into Milliliters: Multiply the number of ounces by 28.35 (equivalent in grams of 1 avoirdupois ounce); then divide the product by the specific gravity of the substance, to obtain the volume in milliliters.

Grains, Drams, and Ounces into Grams (or mL): 1) Divide the number of grains by 15; or 2) multiply the number of drams by 4; or 3) multiply the number of ounces by 28.35. The result in each case equals the approximated number of grams (or mL).

Kilograms into Pounds: Multiply the number of kilograms by 2.2046, or multiply the number of kilograms by 2 and add 10% to the product.

Pounds into Kilograms: Divide the number of pounds by 2.2046, or multiply by 0.4536
