Convert 1000 mL to liters.

Convert 1000 mL to liters.

“milli-” means 1/1000. So, 1000 mL = 1 L

Convert 3542 ft to miles

Convert 3542 ft to miles

Start with what you know: 3542 ftThen state what you want to know: How many miles?There are 5280 ft in 1 mile. Therefore, 5280 ft. = 1 mileSo, 5280 ft/1mile = 1 = 1 mile/5280 ft.

3542 ft. x 1 mile/5280 ft. = 0.6708 miles

Convert 100 cm to meters

Convert 100 cm to meters

“centi-” means 1/100, so 100 cm = 1 meter

Convert 11 inches to feet.

Convert 11 inches to feet.

Start with what you know: 11 inches.Then state what you want to know: How many feet?There are 12 inches in 1 ft. Therefore, 12 inches = 1 ft. So, 12 inches/1 ft. = 1 = 1 ft./12 inches

11 in. x 1 ft./12 in. = 0.92 ft.

Convert 14.6 km to meters

Convert 14.6 km to meters

Start with what you know: 14.6 km.Then state what you want to know: How many meters?There are 1000 m in 1 km. Therefore, 1000 m = 1 km So, 1000 m/1 km = 1 = 1 km/1000 m

14.6 km x 1000 m/1 km = 14,600 m
