Convert 14400 seconds to hours

Explanation

Let's convert 14400 seconds to hours, or s to h as one could put it.

First, we need to calculate the conversion factor using the units respective values. We find 0.0002778.

Then we multiply this conversion factor by the number of seconds. In this case 14400.

Therefore, 14400 seconds is equal to 4 hours.

Formula

1 s≈0.0002778 h

14400 s≈14400 × 0.0002778 h

14400 s=4 h

The second (s) is the base unit of time in the International System of Units.

Definition of the second

It is defined by taking the fixed numerical value of the caesium frequency ∆ν_Cs, the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s^–1.

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.

The length of days on Earth is increasing, drifting further and further from the "ideal" day of 24 hours as the Moon moves away from us. It is the same phenomenon that figure skaters experiment when they stretch their arms out while spinning.

A sexagesimal system

Hours, minutes and seconds are an example of a sexagesimal or base 60 numeral system.

The number 60 is a superior highly composite number, meaning it has a lot of factors. This allows for some simplification when dividing.

Since there are 60 minutes in an hour, the hour can be divided evenly in eleven different ways (with sections of 30, 20, 15, 12, 10, 6, 5, 4, 3, 2 and of course 1 minute).

Coming up with and remembering 60 different symbols would be cumbersome, that is why we write the sexagesimal digit using the decimal system.
