Weight Converter
Compare kilograms, grams, pounds, ounces and several ton definitions in one view. The output helps interpret shipping or product mass labels without calculating gravitational force.

How to use this tool
Enter the mass and its current unit. Distinguish metric tonnes, US short tons and UK long tons; a source labelled only ton needs its definition clarified before conversion.
Results and examples
One metric tonne is 1000 kg, whereas one US ton is 907.18474 kg. Very large or small results may use scientific notation, so read both the exponent sign and the coefficient.
Limitations
- Converting mass to newtons requires gravitational acceleration and is outside this tool.
- Troy ounces used in precious-metal trading differ from avoirdupois ounces.

Frequently asked questions
Are metric tonnes and US tons identical?
One metric tonne is 1000 kg, whereas one US ton is 907.18474 kg. Very large or small results may use scientific notation, so read both the exponent sign and the coefficient.
Does it calculate weight in newtons?
Converting mass to newtons requires gravitational acceleration and is outside this tool. Troy ounces used in precious-metal trading differ from avoirdupois ounces.
