Metric rulers are fairly
easy to read. They deal with centimeters and millimeters only. You wont have to worry much about fractions.
Take a look at the following Metric Ruler.

The longer lines labled with numbers are centimeters, and the shorter lines are millimeters. Since millimeters are 1/10th of a centimeter, if you measure 7 marks after a centimeter, it is 1.7 centimeters long.

Take a look at the following English Rulers.
A ruler marked in 8ths. Every mark is 1/8th of an inch.
A ruler marked in 16ths. Every mark is 1/16th of an inch.
When marking down a distance from a ruler, mark the whole inch, followed by a space, then the fraction of an inch.
For example, 1 1/2, or 2 3/8.
When entering fractions into the conversion calculators, you have to seperate the whole number and the fraction with a + sign.
For example, 1+1/2, or 2+3/8.
