Time Converter

About This Tool

This Time Converter is a versatile tool for converting between various units of time. Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future. The base unit for all calculations is the second (s), one of the seven SI base units.

From the microseconds and nanoseconds used in computing and physics to the familiar hours, days, and years of daily life, this tool provides fast and accurate conversions for a wide range of applications.

Tips & Features

• The Second Standard: The second (s) is the fundamental unit. It is now defined with extreme precision based on the frequency of radiation from cesium-133 atoms.
• Calendar Variations: For units like 'month' and 'year', this tool uses a common average (e.g., a year is 365.2425 days). For precise astronomical calculations, specific year types (like sidereal or tropical) are used, which are also included.
• Leap Years: The Julian and Gregorian calendar systems use leap years to keep the calendar year synchronized with the astronomical year. This converter accounts for this in its definition of a standard 'year'.
