Volume Unit Converter — CBM, Liters, Cubic Feet & Cubic Inches
Answer: Convert volume by first expressing the input in cubic meters: 1 m³ equals 1,000 L, 35.3147 ft³, 61,023.7441 in³, or 1,000,000 cm³.
This converts volume only. Freight chargeable weight and physical weight need a carrier divisor or cargo density.
One cubic meter equals exactly 1,000 liters and approximately 35.3147 cubic feet or 61,023.7441 cubic inches; this converter moves between those units without treating volume as weight.
When to use this converter
Use it when a supplier gives carton, tank, drum, or shipment volume in a unit different from the unit used in your freight quote or warehouse plan. It is especially useful for converting CBM to liters, cubic feet to cubic meters, or cubic inches to cubic meters before comparing packed volume.
Do not use it to convert CBM into kilograms or metric tons unless you also know cargo density. Do not use it as proof that cartons will physically fit a container; loadability also depends on dimensions, orientation, pallets, voids, door limits, and payload.
Required information and process
- Enter the known volume and select its unit.
- Read the equivalent CBM, liters, cubic feet, cubic inches, and cubic centimeters.
- For freight, carry the CBM result into the CBM calculator, CBM to metric ton calculator, or container load calculator only when that next calculation matches your decision.

Frequently asked questions
How many liters are in one cubic meter?
Exactly 1,000 liters. NIST identifies the liter as the cubic decimeter, so 1,000 dm³ equals 1 m³.
How many cubic feet are in one CBM?
Approximately 35.3147 ft³.
How do I convert cubic feet to cubic meters?
Multiply cubic feet by 0.028316846592. For example, 100 ft³ equals about 2.83168 m³.
How do I convert cubic inches to cubic meters?
Multiply cubic inches by 0.000016387064.
Is CBM the same as liters?
They measure the same physical quantity at different scales. One CBM is 1,000 liters.
Can I convert CBM directly to kilograms?
No. CBM is volume and kilograms are mass. You need packed cargo density or actual gross weight.
Can I use liquid capacity as shipping CBM?
Not by itself. Freight CBM normally uses the outer packed dimensions of the drum, IBC, tank, carton, or pallet, not only the liquid inside it.
Is one milliliter one cubic centimeter?
Yes. One mL equals one cm³.
Evidence and verification date
Verified September 28, 2026 against the NIST SI volume guidance and NIST conversion-factor tables. The mathematical unit factors are stable; the tool does not make claims about carrier pricing, cargo weight, or container fit.
