Wheel Converter: Automatic Distance to Degrees Calculator

This tool can be used to easily convert your wheel/tire size information into useful data to be used by your FIRST LEGO League team.

STEP 1: Enter Wheel Dimensions

Input your wheel diameter in millimeters *-OR-* You can click one of the tires commonly used below.

Large Motorcycle Wheel - 94.2×20

EV3 basic tire - 56×28

Motorcycle tire - 81.6×15

Balloon tire - 56×26

Small tire - 43.2×22

STEP 2: Enter Distance Robot Needs to Move

Input the distance you would like the robot to move in either inches or centimeters:
centimeters
inches

STEP 3: Hit the Button to Calculate!

Total distance to travel (in cm)
Circumference of your wheel (in cm) is (π * diameter):
The number of rotations your robot needs to move is (distance to travel ÷ circumference):
The number of degrees your robot needs to move is: (rotations × 360):

STEP 4: Use the Values

Use the rotations or degrees values from STEP 3 in your code. Now you can measure in centimeters/inches and still program in degrees or rotations!
