Converting Units

Converting units

Converting units requires multiplication or division

Examples:

5 dm x 10 = 50 cm ( you multiply by 10 because 1 dm = 10 cm)

50 cm divided by 10 = 5 dm (you divide by 10 because 1 cm = 0.1 dm)

When converting to a smaller unit you get more units so you multiply

1 km = 1000 m because km are larger than m

& 1 km x 1000 = 1 000 m

When converting to a larger unit you get less units so you divide

50 dm = 0.5 dm because dm are smaller than m & 1 dm = 0.1 m.

Converting Rules Converting Rules

1 km = 1000 m (x by 1000)

1 mm = 0.1 cm (divide by 10)

1 m = 10 dm (multiply by 10)

1 cm = 0.1 dm (divide by 10)

1 m = 100 cm (multiply by 100)

1 cm = 0.01 m (divide by 100)

1 dm = 10 cm (multiply by 10)

1 dm = 0.1 m (divide by 10)

1 cm = 10 mm (multiply by 10)

1 m = 0.001 m (divide by 1 000)
