Method
We read objects and weight statements from source articles, normalize them to kilograms, and keep ranges, approximations and the original snippet. Every entry links back to its source.

Data boundaries
We include mass for objects, animals, people and celestial bodies. Fabric areal density, bow draw force and fictional characters are excluded. Weights are approximations from the source, not precise measurements.
Units
The primary unit is the kilogram, with a pound toggle. 1 lb = 0.45359237 kg; 1 short ton = 907.18474 kg.
Corrections
If you spot a wrong weight or have another source, please open an issue in the project repository.
