Thus the sidereal day, the average interval between two successive risings of the same star, is shorter than the mean solar day (see day) by 1/366.242. We only count 365.242 because one rotation is cancelled out for us by our tour around the sun. If we could view the earth from outside the Solar System, we would see that it actually completes 366.242 rotations during one year (one revolution around the sun). Sidereal day: a unit of time used in astronomy, equal to the period of time in which the earth makes one rotation relative to the stars. To convert directly from minutes to hours you multiply by 0.01 6. Simplified, this is the same as multiplying by 60/3600 which is 0.016666667. To convert from minutes to hours multiply the number of minutes by 60 and then divide by 3600. Or you can find the simplified factor by dividing the conversion factor for A by the conversion factor for B. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into seconds then divide by the factor for B to convert out of seconds.

This is the same as dividing 28,800 seconds by 3600 seconds per hour.

Multiply 28,800 seconds by 1/3600 hours per second.

Multiply 120 minutes by 60 seconds per minuteĮxample: Convert 28,800 Seconds into Hours.The table below contains conversion factors to convert any time value into seconds using multiplication.Įxample: Convert 120 Minutes into Seconds Where S is the starting value, C is the conversion factor, andĮ is the converted result. By knowing the conversion factor, converting between units can become a simple math problem: You can use conversion factors to convert a unit of time into another using multiplication or division. This calculator does not consider the extra day in a leap year which has 366 days per year. Years in this time converter are calculated as 365 days per year. This is equal to 365 days per year divided by 12 months per year. Months in this time conversion calculator are calculated using the average of 30.41 6 days per month. You can convert between seconds, milliseconds, microseconds, nanoseconds, days, hours, weeks, months, and years.

Meanwhile, they’ll practice their time-telling skills! That way, students can see how much class time is left. For example, you could display the time when you’re scheduled to go to gym class on the interactive clock. You might also display the online clock in your classroom so that students can compare times to your regular classroom clock. Students can check their own work by toggling the digital display on. Ask students to show a time on the clock and see if they can do it! Or, challenge students to remember what time school ends and have them show that time on the clock. The interactive online clock is a versatile classroom tool. Finally, add some color and interest to your clock by choosing from the colors on the bottom left-hand side. You can also choose between the 12-hour and 24-hour clock using the buttons in the bottom right-hand corner. Turn the digital clock on or off using the button on the bottom right-hand corner. Dash line circles, which can be toggled on or off in the lower left-hand corner, help students see which minute or hour the hands are pointing to. Conveniently, the clock features minute markers around the outside, helping young students learn to read the analog.

The controls are on the top right and left-hand corners. When teaching, turn the hour and minute hands on or off to simplify the clock for early learners. Simply drag the hour and minute hands around the clock to adjust the time. Using the online teaching clock is simple. Both a fun teaching and learning tool, students and teachers can adjust the controls based on the knowledge and skill level of students. Telling time has never been so fun! This online interactive clock merges both analog and digital versions of clocks so that students can practice telling time with each.
