Formula, unit switching and assumptions
Formula: length × width × height ÷ divisor. Dimensions are converted to centimeters before calculation; actual weight is converted to kilograms.
Switch units only when your source measurement is in inches, grams or pounds. Do not mix cm values with an inch unit or the estimate will be inflated.
Use this as planning guidance only; oopbuy final parcel quote and route rules are the source of truth.
