In recent years, the growth of globalization and digital finance has created a demand for seamless tools that can handle both traditional fiat currencies and cryptocurrencies. Existing calculators and platforms typically address either fiat or crypto conversions separately, leading to inefficiency and inconvenience for users who engage in both domains. This research presents the design and implementation of a Crypto and Currencies Calculator, a unified system that integrates real-time fiat-to-fiat, crypto-to-crypto, and fiatto-crypto conversions in a single platform.
