Cartpado, a carton-by-carton DIM-weight calculator

Field notes

For each carton, the page defines volumetric weight as outside length × width × height divided by the selected divisor, then compares it with scale weight. Users can choose whether measurements are used as entered, rounded to the nearest unit, or rounded up. Its example shows a 4 kg carton billed at 6 kg under the stated calculation; the page advises checking the carrier’s own rate guide.
