Convert between thermal conductivity units including W/m·K, BTU/hr·ft·°F, cal/s·cm·°C, and more. Essential for heat transfer analysis
Compute kinetic and gravitational potential energy, work done, and simple work–energy relationships
Energy and utilities work involves constant unit translation between the scales used in physics, engineering specs, and billing systems, and this 10-tool set is built around exactly that.
The Energy Converter and Power Converter handle the everyday translation between joules, kilowatt-hours, and BTUs that comes up when comparing equipment ratings or reconciling a spec sheet with a utility bill. The Photon Energy Converter serves more specialized work — solar and lighting engineers converting between photon energy, wavelength, and frequency when evaluating panel or sensor performance.
On the thermal side, the Heat Transfer Converter, Thermal Expansion Converter, Thermal Resistance Converter, and Thermal Conductivity Converter support insulation, HVAC, and materials work where a spec might be given in one unit system and a calculation needs another. The Fuel Efficiency Mass Converter and Fuel Efficiency Volume Converter help compare fuel consumption figures across metric and imperial units — useful when generator, vehicle, or equipment specs come from different regions. The Work and Energy Calculator ties these together for straightforward energy-balance calculations.
It's a compact, technically focused set — ten tools aimed at the conversion and calculation friction that shows up in energy engineering and utility operations, rather than a general business toolkit.
