Ok here is my quandry
I am a machinist and for the life of me i can not figure out what the conversion for this would be in order to help me further with in the scope of my work..eg.... i have a part that sits on it's edge we will call this 90 degrees if i tilt the part 9 degrees either way how far(in inches) has the part moved from its original postion?
Thanks in advance for all the help you may be able to provide

Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

The amount the part moves from its original position (chord length) depends on the length of the piece being turned. Using inches, the answer will be in decimal inches.
The formula is: 2 R (Sin½ I)
Where:
R = Radius (Length from Pivot Point to End)
I = Central Angle (Degrees)
Example: If the length of the piece being turned is 6":
2 R (Sin½ I)
2*6 (Sin½ 9º)
2*6 (Sin 4.5º)
12 * 0.07845909
0.941509 decimal inches
Because the width of the piece is a factor, be sure to measure on the same side as the angle is tilted so the radius point doesn’t move.
