Mole (unit) 12 lb of C. One lb-mol is equal to , which value is the same as the number of grams in an international avoirdupois pound. In the metric system, chemical engineers once used the "kilogram-mole" (notation "kg-mol"), which is defined as the number of entities in 12 kg of C, and often referred to the mole as the "gram-mole" (notation "g-mol"), when dealing with laboratory data. Late 20th-century chemical engineering practice came to use the "kilomole" (kmol), which is numerically identical to the kilogram-mole, but whose name and symbol adopt the SI convention for standard multiples of metric units –
