Offset Conversion Calculator
Convert wheel offset measurements between inches and millimeters. Calculate proper wheel fitment for your vehicle with our comprehensive calculator.
Step 1: Current Offset
Understanding Wheel Offset
Wheel offset is the distance between the wheel’s mounting surface and its centerline. Positive offset moves the wheel inward, while negative offset moves it outward.
Step 2: Conversion Details
Offset Conversion Formula
1 inch = 25.4 millimeters. To convert inches to mm: multiply by 25.4. To convert mm to inches: divide by 25.4.

Offset Types Explained
Positive vs Negative Offset
Positive Offset: Mounting surface is toward the front (outer side) of the wheel. Common on front-wheel drive vehicles.
Negative Offset: Mounting surface is toward the back (inner side) of the wheel. Common on rear-wheel drive and performance vehicles.
Zero Offset: Mounting surface is exactly at the wheel centerline.
