The conversion factor is 25.4mm per inch.
so, multiply your inch dimension by 25.4 and that is your answer in millimeters.
-----> 3.75 inches x 25.4 = 95.25mm
-----> 7 inches x 25.4 = 177.8mm

To find 76 mm on a tape measure, first locate the metric side of the tape, which is usually marked with millimeters (mm). Count 76 small lines from the zero mark; each line represents 1 mm. Alternatively, if the tape also shows centimeters (cm), you can find 7.6 cm, as there are 10 mm in each cm.

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.
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.
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.
To measure accurately with a tape measure, ensure it is straight and taut against the object being measured. Read the measurement at the closest marking on the tape, and avoid any bends or twists in the tape for precise results.
