Some facts#

• Time allows us to sort events according to their occurence.
• Time is a scalar quantity, which means that it is enough to give one number (values).
• The basic unit of time in the SI system is one second (1 s).
• The definition of a second changes with the progress of physics. In 1967, at the XIII General Conference on Weights and Measures, the second was defined as "the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom at a temperature of 0 K".
• In classical physics time is treated in a special way. It is assumed that time is an independent quantity, which exists independently in isolation from all other quantities.
• In relativistic physics time is one of the coordinates treated analogously to the space x,y,z coordinates (in Cartesian system).

• If you are interested in this page, check our other calculators related to time:
• Time: Date and time formats - date conversion between different formats and according to different calendars in the world,
• Time units - converter of different time units e.g. hours to minutes or vice versa,
• Add or subtract days/months/years to date - check what day it will be for the number of days, months or years you have chosen,
• Work time - check how many hours or working days fall on selected period,
• Dates difference - check how much time has passed the dates you selected,
• Sleep time - check how many hours, days, years etc. you spent sleeping,
• Life time - check exactly how many hours or days of life are behind you,
• Time to holidays - check how much time is left until the next period off from work or school,
• Time to new year - check how much time is left until the end of the current year,
• State pension age - check how much time you still need to work to get the right to retirement.

How to convert#

• Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
Examples:
• 1000000
• 123,23
• 999.99999
• Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
• And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
