1 gallon is approximately equal to 3.78541 liters. Therefore, the volume of water in the drum is: 55\u2009gallons\u00d73.78541\u2009liters\/gallon=208.19755\u2009liters55 \\, \\text{gallons} \\times 3.78541 \\, \\text{liters\/gallon} = 208.19755 \\, \\text{liters}<\/li>\n\n\n\n
The density of water is approximately 1 kilogram per liter, so the mass of the water in the drum is: 208.19755\u2009liters\u00d71\u2009kg\/liter=208.19755\u2009kg208.19755 \\, \\text{liters} \\times 1 \\, \\text{kg\/liter} = 208.19755 \\, \\text{kg}<\/li>\n\n\n\n
To convert kilograms to pounds, multiply by the conversion factor of 2.20462 pounds per kilogram: 208.19755\u2009kg\u00d72.20462\u2009lbs\/kg=458.18\u2009lbs208.19755 \\, \\text{kg} \\times 2.20462 \\, \\text{lbs\/kg} = 458.18 \\, \\text{lbs}<\/li>\n\n\n\n
On Earth, the weight of an object is measured in pounds-force, and since 1 pound-force equals 1 pound of mass under standard gravity (9.8 m\/s\u00b2), the weight of the water will be the same as its mass in pounds. Thus: Weight\u00a0of\u00a0water=458.18\u2009lbf\\text{Weight of water} = 458.18 \\, \\text{lbf}<\/li>\n<\/ol>\n\n\n\n
