Customary Units of Length

Units of Length

feet (ft)

yard (yd)

mile (mi)

inch (in)

1 foot = 12 inches

1 yard = 36 inches

1 yard = 3 feet

1 mile = 1,760 yards

1 mile = 5, 280 feet

We know that 1 mi = 5,280 ft. So we multiply 5,280 x 3 = 15,840

So 3 mi = 15,840 ft.

3 mi = ___ ft

Now we take the product and add the 2 ft that are left.

39 + 2 = 41

So 13 yd 2ft = 41 ft.

Step 2

We know that 1 yd = 3 ft. So we multiply 13 x 3 = 39.

Step 1

13 yd 2 ft = ___ ft

Convert the sum into inches.

1ft = 12 inches.

11 x 12 = 132

132 + 9 = 141 in.

Therefore 11 ft 9 inches = 141 in.

Step 2

Line up the adding sentence. Then add normally.

5 ft 3 in

+6 ft 6 in

11 ft 9 in

Step 1

5ft 3 in + 6ft 6 in = ____ in

Multiple Choice

10 ft 2 inches + 5 ft 3 inches = ___ inches

• 285

• 385

Multiple Choice

3 yd 2 ft+ 5 yd 3 ft = ___ ft

• 29

• 30

• 16

• 15

Convert the difference into inches.

1ft = 12 inches.

2 x 12 = 24

24 + 1 = 25 in.

Therefore 2 ft 1 in = 141 in.

Step 2

Line up the subtraction sentence. Then subtract normally.

3 ft 5 in

-1 ft 4 in

2 ft 1 in

Step 1

3 ft 5 in - 1 ft 4 in = ____ in

Multiple Choice

5 yd 3 ft - 3 yd 2 ft = ___ ft

• 2

• 3

• 7

• 15

Multiple Choice

3 mi - 3 yd - 1 mi 2 yd = ___ yd

• 2,521

Compare Units of Length

Which is more, 1 mile or 2,109 feet?
