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.
To measure the mm of an item you would need to use a metric ruler. The metric ruler has cm and mm on it.
20 mm should still be 20 mm!
With considerable difficulty! With a 30 cm ruler you can easily ascertain that the length is between 2 and 3 ruler-lengths: 600 mm and 900 mm. Maybe you can judge that the the remainder, after 600 mm is less than half of the 30 cm ruler. So that tells you that it is between 600 mm and 750 mm.
a ruler measures 15 cm .1 cm =10 mm .THis means , 1 standard ruler measures 150 mm.
94 mm on a ruler is between 90 mm and 95 mm. On a typical ruler containing both mm and inches scales, where the scales are reversed with respect to each other, 94 mm is opposite 8 5/16 inches.
It is 5 mm. A ruler is used for the purpose of determining sizes from 1 mm to approx 300 mm,=.
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.
half a centimeter. To get a physical idea you need to look at a ruler.
On a standard ruler, 10 mm is equivalent to 0.3937 inches. This conversion is based on the fact that 1 inch is approximately equal to 25.4 mm. Therefore, to find 10 mm on a ruler in inches, you would divide 10 by 25.4 to get the equivalent measurement in inches.
A small ruler is normally 150 mm. Many engineers use these.
To measure the mm of an item you would need to use a metric ruler. The metric ruler has cm and mm on it.
20 mm should still be 20 mm!

a ruler measures 15 cm .1 cm =10 mm .THis means , 1 standard ruler measures 150 mm.
If you are using a ruler marked only in inches then the best sub-division of an onch which approximates to 5 millimetres would be one-fifth of an inch. There are 25.4 millimetres in 1 inch.
show me 21 mm on ruler
