CM because if you want it in mm, do cm first then add a zero.
In centimeters or millimeters
You would use a centimetre.
The length of a unsharpened pencil is 15cm. If you don't believe me measure it yourself.
90 mm
60 x 90 is a length of 5400 cm = 54000 mm. This is NOT the area of 60 cm * 90 cm.
Use a ruler for mm and cm but a metre stick for m.
A ruler or tape measure.
The length of a unsharpened pencil is 15cm. If you don't believe me measure it yourself.
A reasonable length for a [new] pencil is 15 cm. After much [use and] sharpening, it may be reduced to a pencil [stub] only 1.5 cm = 15 mm long.
14
90 mm
12 cm long
Not if all the pencils have to lie straight and neat and parallel, because 16 cm is 1 cm longer than 150 mm.But if the pencil case is more than 5.6 cm wide, then the diagonal is more than 16 cm,and the 16 cm long pencil can lie in it diagonally.
compare it with cm .....mm x 10 cm
1 cm = 10 mm. Start with ruler at 0 and mark ribbon at 30 cm. Then place ruler at the mark and measure 30 cm more and make another mark- you are up to 60 cm or 600 mm. Then place ruler at this mark and measure 5 cm, or 50 mm. Now you have a 650 mm ribbon.
you measure the length of AA pencil or a pen in cm
Units of measure 1 cm = 10 mm 1 mm = 0.1 cm 100 cm = 1 meter
cm
Milliliters are a measure of volume, millimeters are a measure of distance.
