Work out any number of 12 mm bars
How it is worked out
4 soot is 4 eighths of an inch, ½ inch, which is 12.70 mm; it is sold as 12 mm. The weight of a round steel bar in kg per metre is its diameter in millimetres squared, divided by 162.2: 12.70 × 12.70 = 161.3, and 161.3 ÷ 162.2 = 0.994 kg per metre.
One foot is 0.3048 metres, so a foot weighs 0.303 kg and a 40 ft bar 12.12 kg. Real bars can be a little lighter or heavier than the standard weight, so weigh a sample when the exact weight matters.
