About this calculator
Time is measured in seconds in the International System of Units (SI), with both smaller subdivisions (milliseconds, microseconds, nanoseconds) and larger multiples (minutes, hours, days, weeks). Each step uses a fixed ratio: 60 seconds per minute, 60 minutes per hour and 24 hours per day.
This converter uses the second as its base unit. For convenience, a month is treated as 30 days (2,592,000 seconds) and a year as 365 days (31,536,000 seconds). For exact calendar arithmetic involving leap years and varying month lengths, use a dedicated date calculator instead.
