Feet per ton uses the short ton of 2,000 lb. Bars come in 20, 40 and 60 foot stock lengths.
Bar: the size. In the US the number is the diameter in eighths of an inch.
lb per ft and kg per m: the nominal weight. Multiply by the length to get the weight of a bar.
lb per 20 ft bar: the weight of one stock bar. Multiply by the count for an order.
Feet per ton: how much length a short ton of 2,000 lb holds.
Use the chart with the calculator
The chart gives one number for each size. A real job has many sizes and lengths. Add one line to the calculator for each size and length, and it adds the weights for you. Then copy the list, download it as a CSV file, or print it.
For one size, see the size pages: #3, #4, #5, #6, #7, #8.
Rebar weight by size
Each page has the weight per foot or meter, the weight of common bar lengths, and the calculator set to that bar.
