In 1865 Loschmidt used kinetic molecular theory to estimate the number of particles in one cubic centimeter of gas at standard conditions. This quantity is now known as the Loschmidt constant, and the accepted value of this constant is 2.6867773 x 10 25 m-3. The term Avogadros number was first used by French physicist Jean Baptiste Perrin.
