how heavy is a tungsten cube

A tungsten cube is very heavy for its size: a 1-inch cube is about 0.66 to 0.70 pounds, or roughly 300 to 316 grams.

Quick sizes

• 0.5-inch cube: about 38 grams.

• 1-inch cube: about 315 grams, or about 0.7 pounds.

• 1.5-inch cube: about 1 kilogram, or 2.2 pounds.

• 2-inch cube: about 2.5 kilograms, or 5.2 pounds.

Why it feels so heavy

Tungsten is extremely dense, with a density around 19.25 g/cm³, which is why even a small cube can feel surprisingly hefty in your hand. A good rule of thumb is that tungsten weighs far more than steel or lead for the same volume.

Practical takeaway

If someone says “tungsten cube,” the weight depends a lot on the cube’s size, but a desk-sized 1-inch cube is already heavy enough to feel like a small hand weight.
