FreecalcHub provides free online tools to convert various units of weight and mass. Our upcoming calculators include a General Weight Unit Converter for a wide array of units, a Metric to Imperial Weight Converter, a Troy Weight Converter for precious metals, and an Atomic Mass Unit Converter for scientific conversions.
Mass is a fundamental property of matter that measures an object's resistance to acceleration (its inertia). Weight is the force exerted on an object due to gravity. While often used interchangeably in everyday language, mass is constant regardless of gravity, while weight changes depending on gravitational pull. Our calculators typically handle conversions for both concepts as "weight and mass."
Converting weight and mass units is essential in many fields, including cooking, shipping, science, engineering, and international trade. It ensures accuracy and consistency when working with different measurement systems or specialized units.
The two primary systems are the metric system (based on grams, kilograms, and tonnes) and the imperial/U.S. customary system (based on ounces, pounds, and tons).
Troy weight is a system of units of mass primarily used for measuring precious metals like gold, silver, and platinum, as well as gemstones and gunpowder. Common units include the troy ounce and troy pound. Our Troy Weight Converter helps with these specialized conversions.
An Atomic Mass Unit (amu), also known as a Dalton (Da), is a standard unit of mass used to express atomic and molecular masses. It is approximately equal to the mass of one proton or neutron. Our Atomic Mass Unit Converter helps convert between amu and other mass units, primarily for scientific applications.
No, for your privacy and security, all calculations on FreecalcHub.com's conversion calculators are performed client-side within your web browser. We do not store, track, or retain any of the data you enter into our tools.
To convert pounds to kilograms, you divide the number of pounds by approximately 2.20462. Our Metric to Imperial Weight Converter (or a dedicated Pounds to Kilograms converter) will perform this calculation quickly for you.
