There are 20 50kg weights in 1 ton.
One US (short) ton = about 17.86 hundredweights. One UK (long) ton = 20 hundredweights.
There are 20 50kg bags in a ton. This is because a ton is equal to 1000kg, and if you divide 1000kg by 50kg, you get 20 bags. Each bag weighs 50kg, so it takes 20 bags to make up a ton.
