# Calculator for Converting Time.

## Utilizing a Time Calculator

Input your desired time value and corresponding unit of measurement, followed by the desired unit of measurement for conversion. Options include seconds, milliseconds, microseconds, nanoseconds, days, hours, weeks, months, and years.

In this particular time conversion calculator, months are measured using an average of 30.416 days per month, equating to 365 days in a year divided by 12 months in a year. This yields 30.416 days per month.

For years in this converter, calculations are based on 365 days per year. Leap years, which have 366 days per year, are not included in this calculator.

## The Conversion Process

To convert units of time, conversion factors may be utilized via multiplication or division. The conversion factor must be known beforehand in order to solve conversions with ease. The equation is as follows:

**S * C = E**- S denotes the starting value, C represents the conversion factor, and E signifies the resulting converted value.
## Converting Time Units to Seconds

- In the table below, conversion factors for converting time values to seconds are listed:
- To convert minutes to seconds, multiply the number of minutes by 60.

To convert seconds to hours, multiply the number of seconds by 1/3600 hours per second. Alternatively, divide the number of seconds by 3600 seconds per hour.

To convert two units in the left column, say from A to B, multiply by the factor for A to convert A into seconds, then divide by the factor for B to convert out of seconds. Alternatively, find the simplified factor by dividing the conversion factor for A by the conversion factor for B.

An example involving conversion from minutes to hours: multiply the number of minutes by 60 and divide by 3600, or multiply by 0.016666667.

### Sidereal Time

Sidereal day is a unit of time relevant to astronomy and denotes the timeframe it takes Earth to complete one rotation relative to the stars. If viewed from outside the Solar System, Earth actually completes 366.242 rotations during a year, as it revolves around the sun. Humans account for this extra rotation by acknowledging 365.242 rotations per year. Subsequently, the average time between two star risings is shortened by 1/366.242 in comparison to the mean solar day. This culminates in a sidereal day lasting 23 hours 56 minutes 4.09054 seconds, or 86 164.09054 seconds. Similarly to the regular day, a sidereal day is divided into 24 sidereal hours, with each sidereal hour consisting of 60 sidereal minutes, and each sidereal minute containing 60 sidereal seconds. The sidereal hour is composed of 59 minutes and 50.17 seconds, a sidereal minute includes 59.8362 seconds, and a sidereal second is composed of 0.997270 seconds. Traditionally, observatories utilized clocks synchronized to this sidereal cycle, and modern astronomers continue to reference sidereal time in the calibration of telescopes.
