11,700,000mm²/s
That's 105,405× as quick to heat through as copper — nothing on our list beats it. Heat soaks about 1 cm into it in 8.547×10⁻⁶ seconds.

What it means
How fast does heat spread?
Values are typical at room temperature. Diffusivity falls in most metals as they heat up.
The math
How to convert m²/s to mm²/s
To convert square meters per second to square millimeters per second, multiply by 1,000,000.
Example: 11.7 m²/s × 1,000,000 = 11,700,000 mm²/s.
In the other direction, 1 mm²/s = 1×10⁻⁶ m²/s.
