To measure the mm of an item you would need to use a metric ruler. The metric ruler has cm and mm on it.
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.
a ruler measures 15 cm .1 cm =10 mm .THis means , 1 standard ruler measures 150 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.

1.4 cm is the same as 14 mm on a ruler
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 metre ruler is a ruler that measures mm, cm, up to a metre.
A metric ruler is use to measure centimeter and millimeters.1 centimeter (cm) = 10 millimeters (mm) .
A ruler or tape measure.
The normal size of a ruler should be 12 inches or 30cm. (30 cm=300 mm) (1 in=25 mm)
The normal size of a ruler should be 12 inches or 30cm. (30 cm=300 mm) (1 in=25 mm)
To measure in millimeters (mm), use a ruler or measuring tape with markings in millimeters. To measure in centimeters (cm), use a ruler or measuring tape with centimeter markings. For meters (m), use a meter stick or measuring tape with markings in meters. Simply align the start point of the object you are measuring with the zero mark on the ruler or tape and read the measurement at the endpoint.
1 cm is the 1st significant digit on this cm ruler.0.1 cm (= 1 mm) is the 2nd, 0.01 cm is the 3rd and finally0.001 cm (= 0.010 mm =10 mu) gives you the shortest measurable distance in FOUR significant figures, this means it is accurate to measure difference between 0.001 and 0.002 cm
