Converting Between Metric and Imperial Units by Ro...
• Introduction

In this worksheet, we will use rounding to convert between imperial and metric units.

Imperial units can be converted into approximate metric equivalents by knowing the following conversions:

1 m = 3 ft
8 km = 5 miles
1 kg = 2.2 lbs
30 g = 1 ounce
1 litre = 2 pints

Example 1

Approximately how many metres are equivalent to 30 ft ?

1 m = 3 ft
1/3 m = 1 ft
30 × 1/3 m = 30 ft
10 m = 30 ft

Example 2

Approximately how many km are equivalent to 17 miles ?

8 km = 5 miles
8/5 km = 1 mile
17 × 8/5 km = 17 miles
27.2 km = 17 miles
