Are digital tape measures accurate?

The numbers on the tape measure are divided into two rows, one row of numbers is in cm/CM, the other row is in inches, 1CM is about 0.3937 inches, and 1 inch is about 2.54CM, so the shorter the number between the two numbers The distance is in centimeters. The longer one is inches, and the number font of centimeters is also smaller than the number font of inches, 100 cm = 1 meter, and the unit in use is generally cm

Tape measure function

1. Excessive deformation of the tape measure will not fail. The spring in the tape measure is long and can range from fully relaxed to fully tightened. The entire travel of the tape measure is included, and there are margins on both ends so the tape measure doesn't fail.

2. There is no difference between pulling one meter long and two meters long; the spring of the tape measure is very thin, and the amount of deformation when it is tightened is also small, so the reaction force is very small, and the change of force cannot be felt when the ruler is pulled.

Measurement methods

The tape measure tip is loose so we can measure the size. When measuring the size of a tape measure, there are two methods of measurement. One is to hang on objects and the other is to push on objects. The difference between the two measurement methods is the thickness of the iron sheet at the tip of the tape measure. The purpose of loosening the tape measure head is to compensate for the iron piece when the tape measure head is pressed against the object.
