You find a tape measure and take the measurement across the door, then the length of it, then if necessary the thickness.
compare it with cm .....mm x 10 cm
76 millimetres is equal to 7.6 centimetres, or 2.99 inches.
This is not a valid conversion. Square mm is a measure of area. Cubic mm is a measure of volume.
To measure the mm of an item you would need to use a metric ruler. The metric ruler has cm and mm on it.
You find a tape measure and take the measurement across the door, then the length of it, then if necessary the thickness.
The least count of a steel tape measure typically ranges from 0.1 mm to 1 mm, depending on the precision of the tape measure. This means that the smallest measurement that can be accurately read and recorded on the tape measure falls within that range.

A ruler or tape measure.
You probably mean the width of a cassette tape!
25.4 mm = 1 inch18.5 mm = 0.728 inch (rounded)
No. The smallest division on a tape measure is normally a millimetre. So you can see what 4 mm looks like and what 5 mm looks like but you can only make an informed guess at 4.5 mm.
Meter stickI'm thinking you would use a tape measure
take a can and put paper around it then tape it up then measure it in mm
34 millimeters is equivalent to 3.4 centimeters or 0.034 meters
It is a length of 1.9 centimetres.
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.
