ounces (oz)
The ounce derives from the Roman 'uncia', meaning 'one twelfth', originally referring to 1/12th of a Roman pound. However, in the modern avoirdupois system used in the US and UK, an ounce is 1/16th of a pound. This unit is critical for precision in non-metric cooking and for measuring precious metals (though gold uses the 'troy ounce', which is slightly heavier).

grams (g)
The gram was the foundational unit of the original metric system in 18th-century France. Defined as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a meter (1 cm³), it brought logic to a chaotic world of measurements. It remains the standard for cooking, chemistry, and postal services. The gram is the base for the CGS system, which preceded the modern SI system.
