Explanation Given: Given what you have learned in this chapter and the appropriate conversion factors, you can do any unit conversion problem. The following problems have somewhat obscure conversion factors. Use Google or Excel (or any other means) to make the following conversions. a) Convert 100 furlongs to kilometres b) A snail crawls 23 inches per day. Convert to miles per hour. c) Convert 100 drams to ounces. d) Convert 1 hectare to acres. e) Convert 1000 Pascal to pounds per square inch (units of pressure). f) Convert 1 hectolitre to gallons. We can use the following conversion for the given questions. a) 1 Furlongs = 1 8 mile. b) 1 Inch equals 1 12 of a foot and a feet is 1 5280 of a mile. c) 1 ounce = 16 drams 1 dram = 1 16 ounces d) 1 hectare equals 0.01 km 2 and 1 square kilometres equals 247 acres. e) 1 Pascal is equal to 0.000145037738 pounds per square inch (psi). f) 1 hectolitre equals 100 litres and a litre is equal to 0.2641 gallons. Calculation: a) Conversion of 100 furlongs to kilometres We know that 1 furlong is equal to 1 8 of a mile and mile is equal to 1.6093 km. Therefore, we can convert 100 furlongs to kilometres as follows. 1 furlongs = 1 8 mile. 100 furlongs = 1 8 ×100mile = 12.5miles. Therefore, 12.5 miles can be converted in kilometres as follows, 100 furlong = 12.5 miles = 12.5 × 1.6093 = 20.11625 km Thus, 100 furlongs is equal to 20.1 kilometres. b) Conversion of 23 inch per day to miles per hour We know that 1-inch equals 1 12 of a foot, and a foot is 1 5280 of a mile, then 1 inch = 1 12 × 1 5280 miles 23 inches = 23 × 1 12 × 1 5280 miles Therefore, the required conversion is 23 inches per day = 23inch 1day = 23× 1 12 × 1 5280 24hours = 23 12×5280×24 miles/hour = 1 ...
