What thermodynamics units are supported?

We support units for specific heat capacity (J/kg·K), thermal conductivity (W/m·K), thermal resistance, thermal expansion, entropy, and enthalpy.

Who uses thermodynamics converters?

These tools are primarily used by mechanical engineers, HVAC technicians, materials scientists, and physics students analyzing heat transfer and thermal efficiency.

Can I convert between SI and British Thermal Units (BTU)?

Yes, our converters fully support conversions between SI metric units (Joules, Watts) and imperial units like BTUs used commonly in the HVAC industry.

What is specific heat capacity?

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. Our converter easily translates this between J/(kg·K) and BTU/(lb·°F).
