Are you sure it won't strain your brain?
You find a tape measure and take the measurement across the door, then the length of it, then if necessary the thickness.
The answer depends on the tape measure. It is quite likely it is 375 centimetres = 3.75 metres, but it is not possible to be sure.
To measure (for example) a 2 metre long plank of wood: Place the tang at one end of the plank, stretch out the tape along the plank's length, read off the measurement at the other end of the plank. In our example, the tape should read 2 metres.
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.

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.

You probably mean the width of a cassette tape!

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.

take a can and put paper around it then tape it up then measure it in mm
