#150# mm is #1.50# decimeter

There are #10# decimeters in each meter

and #1000# mm in each meter

Hence there are #1000/10=100# mm in each decimeter

Hence #150# mm is #150/100=1.50# decimeter.

#150 mm div 10 div 10 = 150/(10xx10) = 1.5dm#

Although decimeters exist, they are seldom used in this form.
We prefer to use metres, centimetres and millimetres.

We would say 20 cm rather than 2 dm, although the length is the same.

The conversion between the units of length is by a factor of 10 each time.

Multiply by 10 to covert to the next smaller unit or divide by 10 to change to the next bigger one.

#150 mm div 10 div 10 = 150/(10xx10) = 1.5dm#

However decimetres are important because they offer another link between length and capacity.

A cube that is

#10cmxx 10cmxx 10 cm# is the same as #1 dm^3#

It holds exactly 1 litre.

So we have:

#1 cm^3 = 1cc = 1ml#

#1 dm^3 = 1 litre#

#1 m^3 = 1 Kl #

The conversion factor between these is 1000.
