Are tape measures more accurate?

How do accuracy and precision differ?

Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. A classic way of demonstrating the difference between precision and accuracy is with a dartboard.

What is the error on a tape measure?

An error in measurement is the difference between a taken measurement and the known actual value (the accepted true measurement) of what is being measured.

What is the Black Diamond for on a tape measure?

spacing
The black diamonds which appear every 19 3/16” on metal tape measures are for spacing I-beam “timbers.” Several wood-product manufacturers offer I-beam “timbers” as a substitute for solid lumber floor joists. The diamond marks on tape rule blades are for spacing these engineered floor joists in new construction.
