"You could ask ‘if it says 2.5 centimeters on the ruler how many inches is that’? Another question could be, ‘if the ruler says it is 20 millimeters then how many centimeters is this’?

Rulers have long been made of wood in a wide range of sizes. They are not however all wood. Plastics have been used since they were invented; they can be mouldedmolded with length markings instead of being scribed. Metal is used for more durable rulers for use in the workshop; sometimes a metal edge is embedded into a wooden desk ruler to preserve the edge when used for straight-line cutting.

12 inches or 30 cm in length is useful for a ruler to be kept on a desk to help in drawing. Shorter rulers are convenient for keeping in a pocket. Longer rulers, e.g., 18 inches (45 cm) are necessary in some cases. Rigid wooden or plastic yardsticks, 1 yard long and meter sticks, 1 meter long, are also used. Classically, long measuring rods were used for larger projects, now superseded by tape measure or laser rangefinders.

Desk rulers are used for three main purposes: To measure, to aid in drawing straight lines and as a straight guide for cutting and scoring with a blade. Practical rulers have distance markings along their edges.

A type of ruler used in the printing industry is called a line gauge. These may be made from a variety of materials, typically metal or clear plastic. Units of measurement on a basic line gauge usually include inches, agate, picas, and points. More detailed line gauges may contain sample widths of lines, samples of common type in several point sizes, etc."

See my uploaded image. The longest middle line is the half-inch mark. To its left, you will see 1/4 inch mark. The third and fourth shortest line is 1/8 inch and 1/16 inch , respectively.

You read it with GREAT skepticism! If you mean a ruler as in a foot (which is how it evolved-actually determined by King James own foot). I trust only the metal ones with the recessed increments. They are usually divided on one side in some metric format such as tenths of an inch.

Well, your question is not very specific. A lot depends on what type of ruler you are talking about. The most common being the standard ruler for inches and feet and the metric ruler with centimeters and meters. For inches they are usually broken down into eighths or sixteenths of inches, longer marks are for quarter inches or half inches and the numbers are inches. It is similar for a metric ruler, centimeters, decameters, meters etc.

A ruler is generally 12 inches long or one foot in length. The inches are divided into halves, fourths, eighths and even sixteenths with little markings as they go down in progression. The opposite side of the inches in the ruler is the centimetres. Centimetres are further divided into small lines called millimetres. To measure something (or read a ruler), you need to arrange the ruler straight in such a way that the 0 at one end of the thing you are measuring. Look how far the ruler reaches out to the other end of the object. The number that you see in inches or centimetres is the measurement.

The distance between two inches is half an inch. Similarly the distance between two centimetres is half a centimetre. The 'half' is denoted by a medium sized line between two big lines corresponding to the inches or centimetres.
