Question

Convert:
14000 millimetres = ___ metres.

• A. 14
• B. 140
• C. 14000000
• D. 1.4

Answer 1

The correct option is A 14

To convert a smaller unit (mm) to a larger unit (m) we divide by the conversion factor.
Step 1

Convert 14000 mm to cm

We know that 10mm = 1cm
Therefore 14000mm = 14000 ÷ 10

=1400010

= 1400 cm

Step 2

Convert 1400 cm to m

Now we know that 100cm = 1m

Therefore 1400 cm = 400 ÷ 100

=1400100

= 14 m

Answer: option A. 14m
