Most of Locad's carriers charge based on physical weight or volumetric weight, whichever is higher. This is rounded up to the closest weight bracket.

**Physical Weight**

The physical weight of the parcel, including packaging. You can get this value by placing your parcel on a weighing scale. This is sometimes called Actual weight.

**Volumetric Weight**

This is expressed in kg, and is calculated by the following formula:

Length(cm) * Width(cm)* Height * (cm) / Volumetric factor

Depending on the carrier, the volumetric factor is typically a number that ranges from 3500 to 6000. You can find the exact number for each carrier on the Billing > Billing Rates page.

The volume is always calculated as a cuboid. For odd-shaped parcels, the calculated volume will include the empty space.

If there are multiple items in your parcel, they must be packed together into 1 single package.

The Locad system automatically tries to find the smallest possible cuboid shape.

Packaging material (bubble wrap) and carton boxes are also included in the volume.

__Example 1__

Parcel dimensions are 50cm by 25cm by 20cm.

Volumetric factor is 3500.

Volumetric weight = 50 * 25 * 20 / 3500 = 7.14kg

__Example 2__

Parcel shipped is a ball with diameter 10cm.

Volumetric factor is 3500.

Volumetric weight = 10 * 10 * 10 / 3500 = 0.29kg

You will still billed for the empty corners, rather than just the actual volume of the ball.

__Example 3__

Parcel includes 2 items. Items must be packed together.

Item 1 (long and narrow): 100cm by 2cm by 2cm

Item 2 (small cube): 10cm by 10cm by 10cm

When combining the two items, the smallest possible cuboid parcel size would be 110cm * 10cm * 10cm.

The parcel may also be packed as 100cm * 10cm * 12cm, but that is less space efficient. This will depend on the maximum dimensions that the carriers can accept, as well as the availability of boxes or packaging.

Incorrect calculation: ((100 * 2 * 2) + (10 * 10 * 10) ) / 3500 = 0.40kg

Correct calculation: 110 * 10 * 10 / 3500 = 3.14kg

**Chargeable Weight**

Chargeable weight is the higher of either actual or volumetric weight.

__Example 4__

Parcel dimensions are 50cm by 25cm by 20cm.

Volumetric factor is 3500.

Actual weight is 9.2 kg.

Volumetric weight = 50 * 25 * 20 / 3500 = 7.14 kg

Chargeable weight = 9.5 kg

__Example 5__

Parcel dimensions are 50cm by 25cm by 20cm.

Volumetric factor is 3500, and rates are quoted at 0.5 kg intervals.

Actual weight is 4.7 kg.

Volumetric weight = 50 * 25 * 20 / 3500 = 7.14kg

Chargeable weight = 7.5 kg
