Frequently asked questions

Is 18mm the same size as a standard paperclip?
No, 18mm (0.709 inches) is smaller than a standard paperclip, which is typically around 28-33mm long. However, 18mm is close to the width of a paperclip's loop or the diameter of a AAA battery, making it useful for gauging small measurements.
Can I use 18mm drill bits or screws interchangeably with 0.709 inch sizes?
18mm and 0.709 inches are essentially equivalent measurements (the difference is negligible at 0.0005 inches). However, drill bits and fasteners are typically sold in either metric or imperial sizes, so you should match the system your tool or equipment uses rather than trying to convert between them.
