Convert Mass Between Units
The kilogram (kg) is the base unit of mass in the International System of Units (SI). Originally defined in 1795 by the mass of 1 dm³ of water at 0°C, it was later redefined in 1889 as the mass of the international prototype kilogram. In modern times, proposals have emerged to define the kilogram based on fundamental constants such as the Planck constant.
Supported units:
- Metric: kilograms (kg), grams (g), milligrams (mg), metric tons (t)
- Imperial: pounds (lb), ounces (oz), stones (st), tons (short and long)
- Others: carats (ct), atomic mass units (amu), slugs
This converter ensures consistent and precise mass conversions across scientific, industrial, and personal contexts.
