loschmidt is the Loschmidt constant, a number-density reference for an ideal gas at specified standard conditions.
It links molecular counts and gas volume. Pair it with the Avogadro constant, molar volume, and to() for unit conversion.
Standard temperature and pressure conventions vary; always state the reference conditions.
