What are the markings on the ruler and how is it used to measure length?

Answer 1

Rulers go up in mm, cm or inches. You can also get metre sticks that go up to 1 metre. You measure length by putting the 0 mark on the line and then where your line ends is how long the line/shape side is. If you want to measure say the length of a room with rulers you should use steel rulers which start at the end.

A foot is 12" An inch can be divided into smaller parts or fractions. Most tapes/rulers have 1/32 as the smallest mark (or each inch divided into 32 equal parts)from there-1/16, 3/32.1/8,5/32, 3/16, 7/32,1/8,9/32,1/4 etc

Most even marks like eights, sixteenths, quarters, halves and inches are prominent. To get to know them get a tape measure

find 1/16 and count out 16 to 1 inch to see where they are

do the same with eighths (count 8) and quarters (count 4)

Just use smaller fraction if there is one. For instance 2 quarters is 1/2-so you use 1/2. 2/16's is 1/8-so you use 1/8. In between the even increments, use 32's. Once you know the increments in 1 inch, you can measure anything. For length a tape is used which simply tells you how long something is in inches, For example 6' ll 3/4" -six feet, eleven and three quarter inches. Rulers are standard at one foot but same applies.
