The accuracy of a steel rule typically ranges from ±0.5 mm to ±1 mm, depending on the quality and manufacturing standards. Higher-quality rules may offer better precision, while lower-quality ones can have greater variability. Steel rules are generally used for measuring lengths in various applications, providing reliable measurements for everyday use in woodworking, metalworking, and other crafts. However, for highly precise measurements, calipers or micrometers are often preferred.
To take care of a steel rule, keep it clean and dry to prevent rust and corrosion. Wipe it down after use with a soft cloth, and store it in a protective case or drawer to avoid scratches and damage. Avoid dropping or bending the rule, as this can affect its accuracy. Regularly check for any signs of wear or damage and replace it if necessary.

To care for a steel rule, keep it clean by wiping it with a soft, dry cloth after each use to remove dust and moisture that can cause rust. Store it in a protective case or a drawer to prevent bending or damage. Periodically, apply a light coat of oil to the blade to protect against corrosion, especially if you live in a humid environment. Avoid exposing the rule to extreme temperatures or harsh chemicals that could compromise its accuracy and finish.
I have steel rules that are marked down to 1/64 of an inch.
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."

A folding rule provides better accuracy and precision when measuring due to its stiffness, which helps maintain a straight and consistent measurement. In contrast, cloth or steel tapes are prone to bending or stretching, leading to less accurate measurements. The rigidity of a folding rule also enables it to be used for longer measurements without the need for additional support or reinforcement.
