How much does the senior men's hammer weigh in Olympic athletics?

The senior men's hammer in Olympic athletics weighs 7.26 kilograms.

The implement consists of a metal ball attached to a wire and a handle. Its total mass is 7.26 kilograms, equivalent to 16 pounds in the traditional imperial specification. Competitors throw it from a circular ring after making controlled turns to build speed.

The women's senior hammer weighs 4 kilograms, so it is not the same implement used in men's Olympic competition. Junior and youth specifications can also differ by age and governing rules.

The event developed from older Scottish and Irish throwing traditions before entering the Olympic program. Modern hammer throwers are judged by the distance from the throwing circle to the first mark made by the ball inside the legal landing sector.
