How do I convert cm to mm? What to I mult. it by?

Answer 1

1 cm = 10 mm.

If you want to convert 2 cm into mm, then you have to multiply by 10 to 2.
so, 2 cm =20 mm.

Answer 2

There is 100 cm in a metre
There is 1000 mm in a metre

Therefore multiply number of cm by 10 to get mm

Example 1 cm = 10 mm

Answer 3

the metric system goes by tens
there are 100 cm in a metre
and 10 mm in a cm, so multiply the amount of cm by 10 to get the amount of mm.

Answer 4

Thjere are 10 mm in a cm. Multiply it by 10

Answer 5

Multiply by 10. 1 cm = 0.01 m, and 1 mm = 0.001 m. 1 cm / 1 mm = 0.01 m / 0.001 m = 10. So one cm is ten mm.

Answer 6

10mm is 1cm. sooo to convert cm to mm you times it by 10.

example: 2cm = 2 times by 10= 20mm

Answer 7

there are 10mm in 1cm

cm to mm = times by 10
mm to cm = divide by 10

Answer 8

The meter diagram is

km(Kilo Metre)
hm(Hekto Metre)
dam(Deca Metre)
m(Metre)
dm(Deci Metre)
cm(Centi Metre)
mm(Mili Metre)

So, if want to go up one step (e.g. mm to cm) you divide it by 10
if want to go down one step (e.g. cm to mm) you multiply it with 10.

e.g.
2 cm = 2 * 10 mm = 20 mm

8 mm = 8 / 10 cm = 0.8 cm.
