How much does a cubic foot of bronze weight?

Bronze is an alloy, and it can vary in composition.

The density of bronze can be guestimated as approx 8.5 g/cm3

⇒ 1 cu ft of bronze weighs approx 530.64 lbs ≈ 37.9 stones ≈ 4.74 cwt.

1 ft = 30.48 cm

1 cu ft = 1 ft x 1 ft x 1 ft

= 30.48 cm x 30.48 cm x 30.48 cm

≈ 28316.85 cm3

1000g = 1 kg

1 kg ≈ 2.205 lbs

14 lb = 1 stone

8 stones = 1 cwt

⇒ 1 cu ft bronze weighs approx 8.5 g/cm3 x 28316.85 cm3 ≈ 240700 g

= 240700 ÷ 1000 kg

= 240.7 kg

≈ 240.7 x 2.205 lbs
