In the use of steel tape measure, the main reasons for the error are as follows
General steel tape measure thermal expansion coefficient of α = 1.25x10-5, for each meter per degree temperature change of only one in eighty thousand, but the same steel tape measure in the temperature difference between the environment or will produce a large length change, affecting the measurement results. The error of temperature variation has been considered in the equation of ruler length.
