GUTCalc offers SI units for everyday calculations, three types of Natural unit modes where physical constants are set to 1, and also supports Gaussian CGS and Planck units for specialized physics calculations.
GUTCalc features built-in unit checking. If a calculation is inconsistent, it will be flagged in red with an explanatory message, helping users identify and correct algebraic mistakes.
Yes, GUTCalc is designed to perform calculations that extend over many orders of magnitude without overflow. For example, it can handle calculations like exp(10000).
The physical constants in GUTCalc are updated to the latest recommended values, including those from the Particle Data Group 2020 review and CODATA 2018.
Upgrading to Pro allows you to create and manage multiple notebooks for organized calculations, sync notebooks across devices with iCloud, and share notebooks with collaborators.
GUTCalc is available for Mac, iPhone, iPad, and iPod. It requires iOS 11+ and 64-bit devices running iOS 10 or later for certain advanced features.
