Understand Metric and Imperial Equivalences
Here are some approximate metric/imperial equivalents that will help you with this activity:
3 ft is approximately 1 m.
5 miles is approximately 8 km.
2 lbs are approximately 1 kg.
1 oz is approximately 30 g.
2 pints is approximately 1 litre.
Approximately how many grams are equivalent to 4 oz?
1 oz = 30g
4 oz = 4 × 30 = 120 g
Approximately how many km are equivalent to 100 miles?
5 miles = 8 km
100 miles = 160 km (multiply each side by 20)
Now, let's put your understanding of approximate equivalences to the test.
