Our Story
Alathasiba started in 2025 as an initiative to provide a comprehensive set of calculators and converters in Arabic. We noticed a lack of Arabic websites providing integrated calculation solutions and wanted to bridge this gap.
Since its launch, the site has evolved to include dozens of specialized calculators in the fields of mathematics, engineering, finance, conversions, and health. We are constantly striving to expand our range of tools to meet the diverse needs of our users.

- Provide accurate and easy-to-use calculators in Arabic and English
- Help students and professionals complete their tasks quickly and efficiently
- Simplify complex calculations through easy-to-understand user interfaces
- Provide high-quality free services to users worldwide

Transparency & Sources
Alathasiba is a free, bilingual (Arabic/English) calculator site: every tool runs on publicly documented formulas, and live data comes from authoritative sources such as the European Central Bank reference rates and the EU VIES VAT validation system. Each calculator is checked against hand-computed reference cases before it is published, and our travel datasets are re-verified at least quarterly — the verification date is stamped on the pages that use them.
