Then, look at the other marks on the ruler and find the number that corresponds to the length of the object or distance. To read a ruler in centimeters, line up the 0 cm mark on the ruler with the object or distance that you are measuring. Learning how to read a ruler in centimeters can be helpful when measuring the size of objects or distances. In the metric system, a ruler is usually labeled in centimeters.

If you are measuring in centimeters, find the centimeter line that corresponds to the size you are measuring. For example, if you are measuring in inches, find the inch line that corresponds to the size you are determining. Once you have identified the unit of measurement, look for the line on the ruler that corresponds to the size you are determining. If you are looking at a ruler that has both inches and centimeters, make sure to identify which unit of measurement each line on the ruler represents. On one side of the ruler, there are usually inches (in), while on the other side there are usually centimeters (cm). When you are looking at a ruler, the first thing you need to do is identify the units of measurement. Rulers are typically made from metal or plastic and are either linear or curved.
It has a straight edge and a graduated scale along one or both of its edges, marked in units of measurement. What is a Ruler?Ī ruler is an instrument used to measure the length or width of objects.
For example, 8 cm would be read as eight centimeters. If a number is not a fraction, it is read as the number itself. For example, 2.5 cm would be read as two and five-tenths of a centimeter. That way you are.In centimeters, fractions are read left to right. Best bet is to go to the information desk and find out for sure. Should be the mark next behind the 1/2 inch mark as 1/2 is 4/8. If you have a 12 inch ruler cut the ruler in half or any dollar bill is exactly 6 inches. The location shown is 1/8 inch beyond the 1 inch mark. Where On A Ruler Is One Eighth Of An Inch?

The imperial system is the system of units first defined in the British Weights and Measures Act of 1824, and 187 years on, it is still used, particularly with older generations in the UK and the USA have a slightly different version of the imperial system called The United States customary system. Other measurements included in the system include the centimetre, kilometre, millimetre, grams, seconds, Degree Celsius, square meter, hectare, litre, Newton, kilopascal, watt and kilowatt, ampere and kilojoule and megajoule.ĭespite the fact that the metric system is the system of measurement for almost the whole world, the imperial system is still widely used throughout Britain and America and this includes the use of inches. France was the first to adopt it in 1799 and it is now the basic system of measurement used in almost every country in the world the United States being the only industrialised country yet to adopt the International System of Units as its predominant system of measurement. The centimetre and millimetre are part of the metric system an international decimalised system of measurement. It will not be perfectly accurate, but if you count five little lines across on the ruler, one third of an inch will be slightly past the fifth line. There will be 16 lines between an inch, and a third of 16 is 5.33cm.

Alternatively, on your ruler on the inches side you will see lots of little lines between each full inch. There are 10mm markings between each centimetre on a ruler, so between the eighth and ninth millimetre, you will have one third of an inch.
