About Taurang

Taurang is a free library of more than 800 online calculators, unit converters and text utilities built to give exact answers quickly — without sign-ups, paywalls or tracking-heavy pages.

Our mission

People reach for an online tool when they need an answer now: the monthly payment on a car, how many cups are in a liter, whether a password is strong enough. We believe that answer should be correct, instant and explained. That is why every Taurang page combines a working tool with the formula behind it, a worked example, a chart and plain-language guidance.

What makes Taurang different

• Accuracy first. Tools use published standards — exact unit definitions (for example 1 inch = 2.54 cm exactly), standard amortization math and validated health equations. Our test suite checks results against known reference values.
• Privacy by design. Calculations happen in your browser. We do not receive the numbers or text you enter.
• Built for every screen. Pages are lightweight, accessible and fast on mobile connections.

How we build and review tools

Each tool is defined from its source formula, implemented once in a shared calculation library, and tested automatically. When standards change or a user reports an issue, we fix the shared library so every affected page improves at once. Read our editorial and accuracy policy for details.
