Usually on one side they are centimetres (numbered) with millimeters (marked but not numbered). On the other side there are inches (numbered) with eighths or tenths or sixteenths or even thirty-secondths (marked but not numbered).

The measurement of 4.55 on a ruler indicates a length of 4.55 units, typically in inches or centimeters, depending on the type of ruler being used. This means it is 4 whole units and an additional 0.55 of the next unit. On a ruler marked in inches, 0.55 would be slightly more than half an inch, while on a centimeter ruler, it would be just over 5.5 millimeters.
You measure length in many ways: using a ruler or yardstick, using a string or tape measure, using a machine to drive or fly over a distance, or using a satellite. Length is measured in units such as centimeters, meters, kilometers, or inches, yards and miles.
You can convert units of length to units of length, and units of area to units of area. But it doesn't make sense to convert between units of length and units of area.
The units of length on a ruler are typically in inches and centimeters. Each inch is divided into smaller units, such as eighths or sixteenths, while centimeters are divided into smaller units called millimeters.

On a ruler using the metric system, you would typically find units such as centimeters and millimeters. These units are used for measuring length and are based on powers of ten for easy conversion. The metric system is widely used in many countries around the world.
A ruler or a metric tape measure is commonly used to measure length in the metric system. These instruments typically have units of centimeters or millimeters for more precise measurements.
The average length of a ruler is 12 inches.
