About this converter
Time conversion is one of the most common real-world calculations, and this converter makes every unit relationship instant. The second is the base unit of the International System of Units, and every other measure — minutes, hours, days, weeks, months, years, decades, centuries, millennia — is a fixed multiple of it. Larger intervals roll into each other predictably: 60 seconds make a minute, 60 minutes make an hour, 24 hours make a day, 7 days make a week, and 365 (or 366) days make a year. This tool supports far more granular units too, from picoseconds and nanoseconds used in electronics and computing, to microseconds and milliseconds measured in benchmarks and network latency, all the way up to centuries and millennia used when studying history and geology. Because every value is expressed against a shared base, the converter returns exact results for any pair — converting seconds to years, hours to weeks, or milliseconds to days all resolve precisely. Use it for scientific work, time-based program logic, project planning, payroll or travel calculations, or simply to double-check a duration you need to reason about in a different unit.
