1 cm³ comparison

How heavy is one cubic centimetre?

For a 1 cm³ sample, the density value in g/cm³ is numerically equal to its mass in grams. This makes density differences easier to picture.

How to read this comparison

Pure elements, not alloys

Steel, stainless steel, brass, and other alloys can have different density and melting behavior. This page compares pure elements.

Density depends on conditions

The source reports density at room temperature. Temperature, pressure, purity, and crystal structure can change measured values.

Why ratios are disabled for °C

Zero degrees Celsius is an arbitrary reference, so saying one melting point is “twice” another is not physically meaningful. The page uses the temperature difference instead.

Relative atomic mass has no unit

It is a ratio relative to one twelfth of the mass of a carbon-12 atom. CIAAW values may include uncertainty or natural isotopic variation.
