When should I use this relativistic calculator instead of a standard kinetic energy calculator?

Use this relativistic calculator when the object's velocity is at least 1% of the speed of light. At lower speeds, the standard KE = 1/2 mv² formula is sufficiently accurate, but relativistic effects become noticeable and require the Einstein-based approach offered by this tool.

What units are used for the kinetic energy output?

The kinetic energy result is expressed in joules, which is the standard SI unit for energy. The calculator internally handles the conversion from the mass and velocity inputs to provide the energy value in joules.

Can I input mass and velocity in any units I choose?

The calculator expects mass and velocity inputs in standard units compatible with the joule output. Users may need to convert their values to kilograms and meters per second (or fractions of light speed) to ensure accurate results, as the tool is designed for these specific units.

What happens if I enter a velocity lower than 1% of light speed?

If the velocity is lower than 1% of light speed, the calculator indicates that you can use the regular kinetic energy calculator instead, as relativistic effects are negligible at such low speeds and the standard Newtonian formula provides accurate results.
