CBM Calculator | Cubic Meter Calculator for Shipping

CBM stands for Cubic Meter. It’s how the freight industry measures cargo volume. Ocean carriers price shipments by CBM, warehouses charge storage by CBM, and customs documents list cargo in CBM. If you’re shipping internationally, you need to know this number.

Measure your carton in centimeters. Multiply length × width × height, then divide by 1,000,000 to get CBM. For a full shipment, multiply one carton’s CBM by the total carton count. Use this number to plan container loads and estimate inbound freight costs.

Actual weight is what the scale reads. Volumetric weight is based on the space a package occupies. Carriers bill the higher of the two, called chargeable weight. Enter both figures and the calculator marks which one applies.

Air freight is expensive and space on planes is limited, so carriers use a stricter formula (divide by 6,000). Ocean freight has more room, so the formula is more forgiving (1 CBM = 1,000 kg). This is why bulky, lightweight items cost way more to ship by air.

About 33 CBM of internal space. Real-world capacity usually runs 25 to 28 CBM once carton shapes, stacking limits, and pallet configurations apply. Our estimates account for typical utilization rates.

It depends on box size. A standard 40ft container holds about 67 CBM. A carton measuring 50cm × 40cm × 30cm has a volume of 0.06 CBM, meaning roughly 1,100 cartons of that size fit in a 40ft container.

A container one foot taller than standard, about 9’6″ inside instead of 8’6″. Same length and width. You get roughly 13% more volume. Good for light, bulky products like furniture, textiles, or packaged foods.

A refrigerated container with built-in cooling. The insulation and cooling unit take up space, so you get less cargo volume than a regular container the same size. A 40FT Reefer holds about 59 CBM versus 67 CBM for a standard 40FT.

They’re planning estimates, not guarantees. Actual capacity depends on your carton dimensions, whether you’re using pallets, and how well everything stacks. Use these numbers for budgeting and initial planning. Your freight forwarder will give you exact loading plans.

Yes. Calculate your total CBM to figure out container needs, estimate shipping costs, and make sure your carton dimensions work for Amazon’s requirements. Especially useful when you’re planning large inventory replenishments.

Yes. No signup, no credit card, no limits. Calculate as many shipments as you want.

Centimeters, millimeters, inches, feet, or meters. Pick from the dropdown next to each dimension field. The tool converts everything to CBM automatically.

Enter dimensions for one carton and set the quantity to your total carton count. If your shipment mixes box sizes, add each size as a separate row and the calculator totals them.

Depends on the shipping method. For ocean freight LCL, carriers typically charge by CBM or weight-ton (1,000 kg), whichever is greater. For air freight, volumetric weight is the standard. Get both numbers from our calculator so you can compare.

Sort of. Ocean freight rates are usually quoted per CBM, so once you have your CBM you can multiply by the rate. But rates vary wildly by lane, season, and carrier. Use CBM to compare quotes—not to guess what shipping will cost.

Yes, CBM calculation directly determines your warehouse space needs. When you know your total CBM, warehouses can tell you exactly how many pallet positions you need and what your storage costs will be. It’s the foundation for planning storage capacity and pricing. We have created a warehouse storage space calculator that helps you determine your requirements instantly.

CBM estimation absolutely impacts your pallet calculations. It shows how efficiently your products stack and how much vertical space you’re using. Two shipments with the same CBM might need different numbers of pallets depending on how the products are configured and stacked. Calculate your pallet configuration perfectly to make your fulfillment operations effortless.

You can calculate CBM for any product category. Whether it’s standard boxes, apparel, electronics, oversized items, or irregularly shaped products, the calculation is the same. You multiply length times width times height and convert to cubic meters.

A reefer is a refrigerated container with insulated walls and a built-in cooling unit. These reduce usable internal space by roughly 15% compared to a standard container. A 20FT reefer holds ~28 CBM and a 40FT reefer holds ~59 CBM.

Frozen food, fresh produce, dairy, pharmaceuticals, nutraceuticals, supplements, and flowers. Any cargo with a temperature-controlled specification during transit qualifies for cold chain shipping in a reefer container.

One CBM equals a box measuring 1 meter on all sides: 1m × 1m × 1m. In practical terms, that is roughly the size of a standard washing machine carton or about 35.3 cubic feet. Most air freight shipments are 1 to 5 CBM. Most LCL ocean shipments start at 1 CBM.

For ocean freight, 1 CBM equals 1,000 kg of volumetric weight. Carriers charge whichever is higher between actual weight and volumetric weight. A shipment lighter than 1,000 kg per CBM gets charged by volumetric weight.

CBM stands for cubic meter. It is the standard volume unit in freight. Ocean carriers price by CBM, warehouses charge storage by CBM, and customs paperwork lists cargo in CBM.

Multiply length, width, and height in meters. For centimeters, multiply the three dimensions and divide by 1,000,000. Multiply the result by your carton count for total shipment CBM.

A standard 40ft container measures 12.03m x 2.35m x 2.39m internally, giving 67.7 CBM. A 40ft High Cube reaches 76.3 CBM. Real usable volume runs 10 to 15 percent lower.

Multiply CBM by 35.315. One cubic meter equals 35.315 cubic feet. Ocean freight quotes use CBM while US domestic and LTL carriers quote in cubic feet.
