Mass is the measure of the amount of matter in an object and its resistance to acceleration (inertia). The SI base unit is the kilogram (kg), now defined by fixing the Planck constant at h = 6.62607015 × 10⁻³⁴ J·s. Mass differs from weight: weight is the gravitational force acting on a mass (measured in newtons), while mass remains constant regardless of location. Common mass units include gram (g), milligram (mg), tonne (t = 1,000 kg), pound (lb), and ounce (oz).

Attogram (symbol: ag) is a metric unit of mass equal to one quintillionth (10^-18) of a gram. One attogram is exactly equal to 1 × 10^-21 kilogram, 0.001 femtogram, or 1,000 zeptograms. The attogram is used to express extremely small masses in nanotechnology, molecular biology, analytical chemistry, and particle science, where measurements often involve individual molecules, nanoparticles, and microscopic particles. It is commonly converted to femtograms and zeptograms for high-precision scientific calculations.

An ounce (oz) is a unit of mass in the imperial measurement system, commonly used in the United States, United Kingdom, and other English-speaking countries. In jewelry, precious metals, and gemstones, the ounce serves as the standard for weight specification, pricing, and certification. One ounce equals approximately 28.35 grams. The ounce appears on jewelry certificates, international shipping documentation, and precious metals trading platforms. For anyone buying or selling jewelry internationally, understanding ounces is essential since most global markets and certification bodies reference ounce-based weights.
