2
Standard Measurement All measurement takes into account space which remains constant. Unlike the metric system, standard measurement is not based on tens and does not use meters, centimeters or millimeters.

3
The standard measurement system is still used by most woodworkers. The inch is divided into fractions. Give an Inch This represents the inch scale. 0 1

4
0 1 0 1 Dividing the Inch Let’s bend the inch into a circle and look at it as a pie graph.

5
Dividing the Inch 0 1 Let’s bend the inch into a circle and look at it as a pie graph.

6
Dividing the Inch Let’s bend the inch into a circle and look at it as a pie graph.

7
One Half Cut the circle into two parts. ½ means one of two (parts). 1/2 is also 8/16, 4/8, & 2/4, but never use those terms to describe 1/2. Always reduce the fraction.

8
One Fourth In four parts (quarters or fourths). ¼ means one of four. 1/4 is also 4/16 & 2/8, but never use those terms to describe 1/4. Always reduce the fraction.

9
One Eighth Dividing into eight makes eight parts. 1/8 is one of eight. 1/8 is also 2/16, but never use those terms to describe 1/8. Always reduce the fraction.

10
One Sixteenth Sixteen parts, usually the smallest division used in our woodworking class. 1/16 is one of sixteen.

11
One Half Inch Cut into two parts. ½ is one of two. 0 1

12
One Quarter Inch Cut into four parts. ¼ is one of four. 0 1 To help see groupings, the dividing lines are at different heights. 1/2 inch is still easy to determine. Because we measure space, one forth can fall anywhere.

13
One Eighth Inch Cut into eight parts. 1/8 is one of eight. 0 1 Notice that because of the different lengths of the dividing lines, ¼ and ½ are still easy to distinguish. Like previous space, 1/8 can be measured anywhere.

14
One Sixteenth Inch Cut into sixteen parts. 1/16 is one of sixteen. 0 1

15
One Sixteenth 0 1 1/16

16
One Eighth 0 1 1/8

17
Three Sixteenths 0 1 3/16

18
One fourth 0 1 1/4

19
Five Sixteenths 0 1 5/16

20
Three Eighths 0 1 3/8

21
Seven Sixteenths 0 1 7/16

22
One Half 0 1 1/2

23
Nine Sixteenths 0 1 9/16

24
Five Eighths 0 1 5/8

25
Eleven Sixteenths 0 1 11/16

26
Three Fourths 0 1 3/4

27
Thirteen Sixteenths 0 1 13/16

28
Seven Eighths 0 1 7/8

29
Fifteen Sixteenths 0 1 15/16

30
One Inch 0 1

31
Some things to remember! The standard system uses fractions. 12 inches equals one foot. Reduce fractions to their lowest terms. Count space not lines. Practice makes measuring easier.
