Physics

Convert units of force such as Newton (N), Kilogram-force (kgf) and Pound-force (lbf).

Convert atomic-scale energy units such as electron volts (eV) to Joules (J). Use in nuclear and quantum physics.

Convert temperatures between Kelvin, Celsius and Fahrenheit scales. Essential for physics, chemistry and thermodynamics.

Convert between degrees, radians and grads. Fundamental to geometry, trigonometry and engineering.

Convert values between SI prefixes (kilo, mega, milli, micro, nano) with exact factors.

Convert radiation units (Sv, Gy, rem, rad) for study and technical reference.

Convert magnetism and magnetic field units with standard relationships for technical use.

Convert frequency to wavelength (and vice versa) considering medium (vacuum/air).

Convert concentration units (mol/L, g/L, ppm, ppb) for study and technical use.

Convert school and academic grades between systems in different countries. GPA, letter and numeric scales.
