About the project

Calculator as a helper tool

The website was created to save time on everyday conversions and ballpark estimates. It gives you a quick answer, but the final decision and validation is always up to you.

Helper for quick estimates

Calculator brings the most common converters and calculators together. It is perfect when you need an approximate answer for home, school, or work tasks in a few seconds.

Updated data without accounts

VAT rates, exchange data, and preset values are reviewed on a regular basis. Everything stays free to use, with no registration or unnecessary data collection.

Transparent approach

Each card explains what assumptions it uses. Whenever a formula is simplified, we mark it directly next to the result so you know how to interpret it.

Important notes

Advisory disclaimer

Results are indicative only and must not be treated as financial or legal advice. Always double-check key numbers before making commitments.

Data sources

We monitor public sources and official releases, yet changes can happen between updates. Validate critical parameters with the latest legislation.

User responsibility

Every visitor is responsible for how they use the calculations. The website cannot be liable for losses caused by wrong inputs or misinterpretation of outputs.
