A carat is a unit of mass for gemstones equal to exactly 200 milligrams (0.2 grams). The carat takes its name from the carob seed, once used as a counterweight for weighing gems. The metric carat of exactly 200 mg was adopted internationally in the early 20th century to standardize the gem trade.

Common uses of carats include: Diamond and gemstone weight; Jewelry pricing and grading; Pearl and precious stone trading; Gemological certification.

A metric ton (tonne) is a unit of mass equal to 1,000 kilograms or approximately 2,204.6 pounds. The tonne was adopted as a non-SI unit accepted for use with the SI.

Common uses of metric tons include: Cargo, freight, and shipping weights; Industrial and agricultural production output; Vehicle and machinery mass; Carbon emission accounting (tonnes of CO₂).
