📘 About the Weight

This weight converter changes a mass from one unit to another across 69 units: metric units (milligrams, grams, kilograms, quintals, tonnes), US and imperial units (ounces, pounds, stone, hundredweights, short and long tons), troy units for gold and silver, gemstone carats, and traditional units from South Asia (tola, masha, ratti, seer, maund, pavan), China, Hong Kong, Japan, Korea, Thailand, Malaysia, the Middle East, Russia, Europe and Latin America — plus scientific units from the atomic mass unit to the solar mass.

Pick the units, type a value and the answer appears with the conversion both ways, the formula and handy values. Every pair of units also has its own page, such as kg to lbs or tola to grams, with a conversion table and worked examples.
