Virtual address page number calculator

The Virtual address page number calculator computes virtual address page number from the relation page number = floor(address / page size). It takes 2 inputs (virtual address, page size in bytes) and returns the page number. Because this is a pure mathematical or physical formula rather than a jurisdiction-specific rule, the result never changes over time: the same inputs always produce the same answer, so you can rely on it whether you are checking homework, sizing a design, or sanity-checking another tool. Enter your values in the fields below and the result updates instantly; you can also share a permalink that pre-fills the exact calculation, which is useful for teaching, reports, or collaboration. For example, with virtual address = 0, page size = 4096 bytes, the page number works out to 0, and the worked example further down the page shows every step so you can follow the arithmetic and reproduce it by hand. The method is the standard form documented by Documented methodology, and the figure above each result carries the date it was last verified.
