The Philippine peso, also referred to by its Filipino name piso (Philippine English: /ˈpɛsoʊ/, /ˈpiː-/, plural pesos; Filipino: piso [ˈpiso, pɪˈso]; sign: ₱; code: PHP), is the official currency of the Philippines. It is subdivided into 100 centavos or sentimos in Filipino. As a former colony of the United States, the country used English on its currency, with the word "peso" appearing on notes and coinage until 1967. Since the adoption of the usage of the Filipino language on banknotes and coins, the term "piso" is now used. From September 2017 to 2 August 2018, the ISO 4217 standard referred to the currency by the Filipino term "piso". It has since been changed back to "peso".
