Einstein Calculators

Einstein Calculators was developed to provide high-precision relativistic physics computations suitable for professional and commercial use. Many existing tools lack the sensitivity, accuracy, or clarity required in scientific, engineering, and research environments. The suite includes six calculators—mass–energy conversion, relativistic kinetic energy, time dilation, gravitational time dilation, relativistic mass, and length contraction—each optimized for precise numerical output. These tools support users who require dependable, high-sensitivity results: scientists, engineers, aerospace professionals, academic institutions, technical educators, and organizations working with relativistic effects. The goal is to offer a robust and accurate resource that performs complex calculations quickly and consistently, enabling both technical and commercial applications without unnecessary friction. Feedback on additional features or expanded capabilities is welcome.
