What is melting temperature (Tm)?

Melting temperature is the temperature at which a solid transitions to a liquid at standard atmospheric pressure (1 atm). It equals the freezing point for a pure substance and is a fundamental physical property used in materials science, chemistry, and engineering.

How accurate are the values in this table?

Values are taken from standard chemistry references (NIST, CRC Handbook). Melting points can vary slightly due to purity, pressure, and measurement method, so treat them as reference values rather than exact laboratory measurements.

How do I convert Celsius to Kelvin?

Add 273.15 to the Celsius value. For example, 0 °C = 273.15 K, and 1064 °C (gold) = 1337.15 K. The tool performs this conversion automatically.

Why do metals have such high melting points compared to organic substances?

Metals are held together by metallic bonds — a "sea" of delocalized electrons — which require a lot of energy to break. Organic substances like wax or sugar are held by weaker intermolecular forces, so they melt at much lower temperatures.

Can I look up alloys in this tool?

Yes. The table includes common alloys such as steel, brass, bronze, solder, and several aluminum and titanium alloys, alongside pure elements and compounds.

Does atmospheric pressure affect the melting point?

Yes, but only significantly at very high pressures. For most practical purposes at or near 1 atm, the values listed are accurate. Ice is a notable exception — its melting point decreases slightly under high pressure.
