| Term: | Ice equivalent |
| Definition: | A unit, in full the 'metre [of] ice equivalent', that is an extension of the SI for describing glacier mass in specific units as the thickness (in 'm ice eq.') Of an equal mass having the density of ice. Ice equivalents can be converted to kg m-2 by multiplying by the density of ice, and to water equivalents (m w. E.) By multiplying by the density of ice and dividing by the density of water (with sufficient accuracy, 1000 kg m-3). |
