Degrees to Inches

Programming Support
#1

Hello, I am attempting to convert the distance on my DrivePID from degrees to inches. Do any of you have suggestions on how how to accomplish this?

#2

Take your degrees and multiply it by pi/180 (radians conversion) then multiply that by the radius of your wheel in inches.

Wouldn’t it be multiplied by diameter instead of radius?

#4

Nah they are right. Radians * radius = distance. The first step just converts degrees to radians.

Alright so would it look like this? The radius of my wheels are 1.625 inches.

// Degrees to Inches

float degree;

float inch = degree * M_PI/180 * 2.0625;

double desiredValue = inch;

If the radius of your wheels is 1.625, you should be multiplying M_PI/180 by 1.625 instead of 2.0625

Yeah your right, I forgot to adjust the code. So would that be it?
