# What is the dimensional formula of height

Dimensional weight reflects package density, which is the amount of space a package occupies in relation to its actual weight. Dimensional weight may apply to all UPS domestic and international package services.

Determine the package dimensions in inches. For each dimension, measure at the longest point, rounding each measurement to the nearest whole number (for example, 1.00 to 1.49 will be considered 1, and 1.50 to 1.99 will be considered 2).

Multiply the package length (longest side of the package) by the width by the height.  The result is the cubic size in inches.

Divide the cubic size in inches by the divisor to calculate the dimensional weight in pounds. Increase any fraction to the next whole pound.

The divisor varies by rate type: 139 for Daily Rates; 166 for Retail Rates.

Dimensional Weight = (L x W x H) ÷ Divisor

L = Length in inches

W = Width in inches

H = Height in inches

Divisor for Daily Rates = 139

Divisor for Retail Rates = 166
