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.
