kNm3

Kilonewton cubic meter (kNm3) is not a standard SI unit. The notation kN·m^3 may appear in engineering documents as the product of a force unit (kN) and a volume unit (m^3). Unlike kN·m, which denotes torque, or J, which denotes energy, kN·m^3 does not correspond to a widely recognized fundamental physical quantity.

Because it mixes dimensions of force and volume, kN·m^3 does not have a single universal interpretation. Its meaning is entirely context-dependent and must be defined by the source. In practice, if you see kN·m^3, you should look for a defining equation or glossary that clarifies what quantity is being described and how the quantity is computed.

Common contexts and caveats: It may appear in specialized hydraulic, geotechnical, or energy calculations as a coefficient, or as a bookkeeping unit used in an equation that multiplies a volumetric term by a force term. It’s also possible that it is a transcription error for kN·m^2 (torque per area) or for kN·m (torque) or for J (energy). Because the meaning is not universal, misinterpretations are easy if the source does not provide a clear definition.

Practical guidance: If you need to convert or compare values, avoid assuming a universal meaning. Instead, extract the defining relation and perform unit consistency checks. Dimensional analysis can help verify whether the quantity makes sense in a given calculation. See also: Torque (N·m), Energy (J), Volume (m^3).
