Universal Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600))
UT_day = (1/24)*(t_hrs+(t_min/60)+(t_sec/3600))
This formula uses 4 Variables

Variables Used

Universal Time - (Measured in Second) - Universal Time is the mean solar time of the Greenwich Meridian (0° longitude).
Time in Hour - (Measured in Second) - Time in hour can be defined as the ongoing and continuous sequence of events that occur in succession, from the past through the present to the future.
Time in Minutes - (Measured in Second) - Time in Minutes is the time measurement in minutes which is equivalent to 60 seconds.
Time in Seconds - (Measured in Second) - Time in Seconds is the unit of time measured in seconds.

STEP 1: Convert Input(s) to Base Unit

Time in Hour: 168 Hour --> 604800 Second (Check conversion here)
Time in Minutes: 20 Minute --> 1200 Second (Check conversion here)
Time in Seconds: 0.5 Second --> 0.5 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

UT_day = (1/24)*(t_hrs+(t_min/60)+(t_sec/3600)) --> (1/24)*(604800+(1200/60)+(0.5/3600))

Evaluating ... ...

UT_day = 25200.8333391204

STEP 3: Convert Result to Output's Unit

25200.8333391204 Second -->0.291676311795375 Day (Check conversion here)

FINAL ANSWER

0.291676311795375 ≈ 0.291676 Day <-- Universal Time

Position Vector

Go Position Vector = (Major Axis*(1-Eccentricity^2))/(1+Eccentricity*cos(True Anomaly))

Kepler's First Law

Go Eccentricity = sqrt((Semi Major Axis^2-Semi Minor Axis^2))/Semi Major Axis

Mean Anomaly

Go Mean Anomaly = Eccentric Anomaly-Eccentricity*sin(Eccentric Anomaly)

True Anomaly

Go True Anomaly = Mean Anomaly+(2*Eccentricity*sin(Mean Anomaly))

Universal Time

Go Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600))

Reference Time in Julian Centuries

Go Reference Time = (Julian Day-Julian Day Reference)/Julian Century

Julian Century

Go Julian Century = (Julian Day-Julian Day Reference)/Reference Time

Julian Day

Go Julian Day = (Reference Time*Julian Century)+Julian Day Reference

Nominal Mean Motion

Go Nominal Mean Motion = sqrt([GM.Earth]/Semi Major Axis^3)

Mean Motion of Satellite

Go Mean Motion = sqrt([GM.Earth]/Semi Major Axis^3)

Local Sidereal Time

Go Local Sidereal Time = Greenwich Sidereal Time+East Longitude

Kepler's Third Law

Go Semi Major Axis = ([GM.Earth]/Mean Motion^2)^(1/3)

Range Vector

Go Range Vector = Satellite Radius Vector-[Earth-R]

Orbital Period of Satellite in Minutes

Go Orbital Period in Minutes = 2*pi/Mean Motion

Anomalistic Period

Go Anomalistic Period = (2*pi)/Mean Motion

Universal Time Degree

Go Universal Time Degree = (Universal Time*360)

Universal Time Formula

Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600))
UT_day = (1/24)*(t_hrs+(t_min/60)+(t_sec/3600))

What is UTC time zone?

The World's Time Standard: Coordinated Universal Time (UTC) is the basis for civil time today. This 24-hour time standard is kept using highly precise atomic clocks combined with the Earth's rotation.

How to Calculate Universal Time?

Universal Time calculator uses Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600)) to calculate the Universal Time, The Universal Time formula is defined as a time standard based on Earth's rotation. There are several versions of Universal Time, which differ by up to a few seconds. The most commonly used are Coordinated Universal Time (UTC) and UT1. Universal Time is denoted by UT_day symbol.

How to calculate Universal Time using this online calculator? To use this online calculator for Universal Time, enter Time in Hour (t_hrs), Time in Minutes (t_min) & Time in Seconds (t_sec) and hit the calculate button. Here is how the Universal Time calculation can be explained with given input values -> 3.4E-6 = (1/24)*(604800+(1200/60)+(0.5/3600)).

FAQ

What is Universal Time?

The Universal Time formula is defined as a time standard based on Earth's rotation. There are several versions of Universal Time, which differ by up to a few seconds. The most commonly used are Coordinated Universal Time (UTC) and UT1 and is represented as UT_day = (1/24)*(t_hrs+(t_min/60)+(t_sec/3600)) or Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600)). Time in hour can be defined as the ongoing and continuous sequence of events that occur in succession, from the past through the present to the future, Time in Minutes is the time measurement in minutes which is equivalent to 60 seconds & Time in Seconds is the unit of time measured in seconds.

How to calculate Universal Time?

The Universal Time formula is defined as a time standard based on Earth's rotation. There are several versions of Universal Time, which differ by up to a few seconds. The most commonly used are Coordinated Universal Time (UTC) and UT1 is calculated using Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600)). To calculate Universal Time, you need Time in Hour (t_hrs), Time in Minutes (t_min) & Time in Seconds (t_sec). With our tool, you need to enter the respective value for Time in Hour, Time in Minutes & Time in Seconds and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
