Key Stage 3

Meaning

Converting units is when one unit prefix is switched for another.

About Converting Units

The Unit Prefixes are:

kilo (k) - 1000 times bigger.
centi (c) - 100 times smaller.
milli (m) - 1000 times smaller.
micro (µ) - 1000,000 times smaller.

Kilo

To convert from kilo to the base unit you must times by 1000.

5km = 5x1000m = 5000m

12km = 12x1000m = 12000m

3.4km = 3.4x1000m = 3400m

0.53km = 0.53x1000m = 530m

0.082km = 0.082x1000m = 82m

To convert to kilo from a base unit you must divide by 1000.

23000m = (23000/1000)km = 23km

8200m = (8200/1000)km = 8.2km

670m = (670/1000)km = 0.67km

32m = (32/1000)km = 0.032km

2m = (2/1000)km = 0.002km

Centi

To convert from centi to the base unit you must times by 1000.

63000cm = (63000/100)m = 630m

3500cm = (3500/100)m = 35m

940cm = (940/100)m = 9.4m

93cm = (93/100)m = 0.93m

4cm = (4/100)m = 0.02m

To convert to centi from a base unit you must divide by 1000.

7m = 7x100cm = 700cm

15m = 15x100cm = 1500cm

8.2m = 8.2x100cm = 820cm

0.26m = 0.26x100cm = 260cm

0.03km = 0.03x100cm = 3cm

Milli

To convert from milli to the base unit you must times by 1000.

83000mm = (83000/1000)m = 83m

2600mm = (2600/1000)m = 2.6m

170mm = (170/1000)m = 0.17m

22mm = (22/1000)m = 0.022m

6mm = (6/1000)m = 0.006m

To convert to milli from a base unit you must divide by 1000.

4m = 4x1000mm = 4000mm

34m = 34x1000mm = 24000mm

1.9m = 1.9x1000mm = 1900mm

0.73m = 0.73x1000mm = 730mm

0.092m = 0.092x1000mm = 92mm
