Quantity

https://ontology.toxindex.com/v1/Quantity Quantity

A number with a unit. The unit is a product of factors, each an atomic unit raised to an exponent, so any compound unit — milligrams per cubic metre, milligrams per kilogram of body weight per day, fibres per cubic centimetre — is composed from a small closed set of parts rather than enumerated.
