Whenever you are measuring using inches and feet every inch on the ruler, yardstick, or tape measure is exactly the same.
The line below has been divided to show the fractions of an inch which are generally used when measuring.
Fractional-Inch (sixteenths, eighths, quarters and halves)
Decimal-Inch (.250, .500, .750, etc)
Engineering drawings are typically dimensioned in decimal inches as specified by ANSI standard Y14.5M. You will need to refer to the table at the back of "The Big Inch" packet (ALSO on page 570 of your Mechanical Drawing book and available for download below.)
Hint #1 - Each 1/16 inch is equal to .0625
Remember:
Remember:
To find the decimal equivalent of a fraction you divide the numerator with the denominator.
To find the decimal equivalent of a fraction you divide the numerator with the denominator.
1/2 = 0.5
1/4 = 0.25
1/8 = 0.125
1/16 = 0.0625
2/2 = 1.0
3/4 = 0.75
5/8 = 0.625
7/16 = 0.4375
15/16 = 0.9375
7/8 = 0.875
9/16 = 0.5625
3/8 = 0.375

This will be a review for many but a necessary one. Reading a ruler is fundamental to drafting and architecture.
In today's lesson you will create your own ruler at 800% and label it in sixteenth, eighth, quarter and half inch increments.
The process will be demonstrated in class by Mr. Bishoff. Following the demo, if you need more guidance, you can follow the directions from the videos at the right and/or below..
Hint #2 - Be careful. Not all drawings are 1:1. The scale is listed at the bottom of each sheet.
