The least count of a metric rule is determined by the smallest division on the scale of the ruler. To calculate the least count, divide the smallest marked division on the ruler by the total number of subdivisions between two main unit markings. For example, if a ruler has millimeter divisions with half-millimeter markings between each millimeter, the least count would be 0.5 mm.
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 steel rule is most commonly refered to as an engineers rule.
"National Steel Rule's website has information on Steel Rule. Fine-Tools and Helmold may also have information on Steel Rule. Wikipedia has info on general rulers, too."
