Editorial policy
Read the standards used to write, review, correct, and update calculator content.
How this applies
The Trusty Calculator Editorial Team writes original explanations and reviews every formula against primary standards, public agencies, or product documentation. We version formulas and content separately, record meaningful corrections, and never publish invented expert endorsements.
