Glossary:Equivalent per million

Jump to navigation Jump to search

An equivalent weight of an ion or salt per 1 million grams of solution or soil. For solutions, equivalents per million (e.p.m.) and milliequivalents per liter (meq/L) are numerically identical if the specific gravity of the solution is 1.0 as it is for freshwater at 20°C.
