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

IMPERIAL

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

Conversion TablesSimilar comparisons can be made. The following conversion table includes those conversions that are the most widely used.
