Pood is a unit of mass
Mass can be defined as a quantitive measure of the resistance an object has to change in its velocity.In physics, mass commonly refers to any of the following three properties of matter, which have been shown experimentally to be equivalent:...

Together with other units of weight
In science and engineering, the weight of an object is the force on the object due to gravity. Its magnitude , often denoted by an italic letter W, is the product of the mass m of the object and the magnitude of the local gravitational acceleration g; thus:...
of the Imperial Russian weight measurement system, pood was officially abolished by the USSR in 1924. However, the term remained in widespread use at least until the 1940s.
Its usage is preserved in modern Russian in certain specific cases, e.g., in reference to sports weights, such as traditional Russian kettlebell

s, cast in multiples and fractions of 16 kg (which is pood rounded to metric units). For example, a 24 kg kettlebell is commonly referred to as "one-and-half pood kettlebell" (polutorapudovaya girya). It is also sometimes used when reporting the amounts of bulk agricultural production, such as grains or potatoes.
An old Russian proverb reads, "You never know a man until you have eaten a pood of salt with him."
