A ruler is a very common stationary and industrial essential which is used for taking measurements and drawing lines along them. A common stainless steel ruler has two measurements written on it, in inches and centimetres. On one side you can find the measurements in inches, and on the other side they’re in centimetres.
How to use
Using a ruler is very easy. Just put it on the surface of whose length you want to measure or create lines, and then just go on with your task.
Common applications
1. Drawing straight lines
2. Measuring exact lengths and mark points accordingly.
Safety Measures to follow
1. The ruler is pointed at edges, so carry and use it safely.
2. Make sure you’re watching the scale normally to avoid parallax errors in measurements.
