The cubic ton is a measure of volume. It is considered obsolete.
Definitions
A
mass-derived unit of volume is defined by reference to the
density of some material. One common such material is water, used in multiple units. For the cubic ton, the situation is more complex—there are different cubic tons for different materials.
The 1964 Reader's Digest Great Encyclopaedic Dictionary gave the following ton-derived volumes:
The nearest thing to a Standardization cubic ton seems to be the "timber" cubic ton () which is used by freight transport operators in the US.
Conversions
Converting cubic tons (i.e., volumes) to measures of weight presents difficulties because organic materials such as timber vary in density.
Approximation volume conversions, based on a timber cubic ton of 40 cubic feet:
-
1 ton (40 cubic feet) = 1.133
-
1 cubic metre = 0.883 cubic tons (35.32 cubic feet)
