**What decimal of an hour is a second?**

To understand the decimal value of a second in terms of an hour, we need to convert the units of time involved and perform the necessary calculations. Let's break down the conversion and calculations in detail.

1 hour consists of 60 minutes, and each minute is further divided into 60 seconds. To find the decimal value of a second in an hour, we need to determine how many seconds are present in one hour and then express that value as a decimal.

Calculations:

1 hour = 60 minutes 1 minute = 60 seconds

To find the number of seconds in an hour, we multiply the number of minutes in an hour by the number of seconds in a minute:

60 minutes × 60 seconds = 3600 seconds

Therefore, there are 3600 seconds in one hour.

To express the value of a second as a decimal of an hour, we divide 1 second by the total number of seconds in an hour:

1 second ÷ 3600 seconds = 0.0002777778

Hence, a second is approximately 0.0002777778 of an hour when expressed as a decimal.

In simpler terms, this means that a second is approximately 0.0002777778 or 0.00028 (rounded) percent of an hour. It is an incredibly small fraction of an hour, emphasizing the minute scale at which seconds are measured.

It is important to note that this decimal value is an approximation and carries a finite number of decimal places. For precise calculations and applications requiring high accuracy, it is necessary to use more decimal places or consider using scientific notation.
