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).

The Kilogram (kg) is the base unit of mass in the International System of Units (SI) and is one of the most widely used measurement units in the world. It is the standard unit for weighing goods, recording scientific data, conducting international trade, and measuring everyday objects ranging from food products to industrial materials.

One Kilogram is equal to 1,000 grams and is used by governments, businesses, laboratories, manufacturers, and consumers across nearly every country. Modern shipping, engineering, healthcare, education, and commerce all rely on the Kilogram because it provides a universally recognized and consistent measurement standard.

The Kilogram serves as a bridge between local and international measurement systems. Traditional units such as Catty, Tola, Vori, Aana, and many other customary units are often converted into Kilograms when products enter global markets, transportation networks, or regulatory systems. Read more about Kilogram.

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.
