Sobre o Calculadorakeskus
Calculadorakeskus offers free, fast and clear calculators. Our aim is that every calculator works instantly in the browser, shows the resultado understandably and is just as smooth on a phone as on a computer. We do not require registration and we do not collect your calculations — the computing happens in your own browser.
The site covers basic and advanced mathematics tools as well as everyday calculators for managing working time, salary, text length, internet speed and personal finances. The content is continuously developed based on user feedback.
Nossos princípios
- Gratuito e aberto. Todas as ferramentas são gratuitas e podem ser usadas sem conta.
- Privacidade em primeiro lugar. Os cálculos permanecem apenas no seu próprio navegador.
- Clarity. Os resultados e, se necessário, as etapas intermediárias são apresentados de forma compreensível.
- Mobile first. Every calculator is designed to work well on a phone too.
