The large ticks in between the inch markings are half-inch markings, and the distance between an inch tick and a half-inch tick is 1 2 '.
#Presentation on how to read a metric scale ruler full#
The largest ticks on a ruler represent a full inch, and the distance between each large tick is 1. Rulers also come in a variety of lengths, but the most common length is 12″. A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length two common examples are an architect's scale and engineer's scale. Reading a ruler starts with understanding what all the ticks mean. Most rulers are made of wood, metal, or plastic and include imperial, metric, and sometimes both imperial and metric measurements. There are several different types and styles of rulers.

So for example, if I want to make 1:10 into 1:6 it’s. Rulers are relatively short measuring instruments most commonly 12”, and are most useful for measuring the length of small objects. I prefer to keep things metric, and all I have to do is photocopy either the 1:10 face of my scale ruler (or the centimetres on a normal ruler) at a different percentage. The usual plastic type above has a different colour (green, red, black) to assist in finding. In any event it’s useful to have a regular rule included ). They are often used in technical drawing, math & geometry, engineering, carpentry, and print fields. These scale rulers usually include 1:20, 1:25, 1:50, 1:75, 1:100 and 1:125 ( the 1:100 ‘scale’ is basically just a regular centimetre rule in which the centimetres can be read as metres. Rulers are used for measuring a line, and the straight edge allows them to be used for drawing, scoring, or cutting. If you are measuring an object, align it with the left side of the zero mark on the ruler. Make sure you read the ruler from left to right. Between each centimeter (cm) mark, there should be 10 smaller marks called millimeters (mm). Rulers used for precision measurements may be certified by the National Institute Of Standards and Technology, which is a measurement standards laboratory agency of the US government. Rulers are often 30 centimeters long, which are designated by large numbers on the ruler. Rulers are sometimes referred to as a rule or line gauge.
