Imperial Measurements and Conversions
1 inch = 2.54 centimeters
1 mile = 1.6 kilometers
Indicate the measurements using an arrow
IMPERIAL to METRIC1 foot = 12 inches
1 yard = 3 feet
1 mile = 1760 yards
IMPERIAL
2 5/8 inch
5/16 inch 2 3/32 inches
1 1/4 inches
3 7/8 inches
4 3/16 inches4 1/16 inches
Perform the indicated operations:
(d) 2.5 feet to the nearest inch(c) 24m - 870 cm - 4350 mm
(a) 76 mm + 12 cm (b) (5 yds 1 ft) x (2 yds 2 ft)
(b) (5 yds 1 ft) x (2 yds 2 ft)
Before performing calculations that involve two different length units, convert either one of the units or both so that the units are the same. (Most often use the smaller units.)Perform the following calculations:
3 mi - 250 ft = ___________________
12 mm x 4.3 cm = ___________________
1 foot = 12 inches
1 yard = 3 feet
1 mile = 1760 yards

Before performing calculations that involve two different length units, convert either one of the units or both so that the units are the same. (Most often use the smaller units.)
A roll of fencing is 90 m long and someone buys 536 cm. How much is left on the roll?
Before performing calculations that involve two different length units, convert either one of the units or both so that the units are the same. (Most often use the smaller units.)Perform the following calculations:
2 m + 75 cm = ___________________
3 ft 2 in + 7 ft 11 in = ___________________
1 inch = 2.54 cm 1 mm= 0.04"1 foot = 30.48 cm 1 cm = 0.39"1 yard = 0.914 m 1 m = 39.37" = 3.28'1 mile = 1.61 km 1 m = 1.09 yd1 km = 0.621 mi
