Best Answer

Yes, the predominant units are all still metric, although cosmologists exploring the earliest instants after the big bang often use units of planck time instead, but this of course is still based on the metric system.

+++

The only other two units of time relevant in Astronomy and Geology are the Year and the second, and the Years are counted as indivisible although the second may be divided into its milli- and smaller divisions for particular calculations.

What does it mean when one number is divisable by another number?

Divisibility RulesA number is divisible by another number if it can be divided equally by that number; that is, if it yields a whole number when divided by that number. For example, 6 is divisible by 3 (we say "3 divides 6") because 6/3 = 2 , and 2 is a whole number. 6 is not divisible by 4, because 6/4 = 1.5 , and 1.5 is not a whole number. It is often useful to know whether a number divides another number. To check divisibility, one can always do the division out by hand and see if the result is a whole number. However, if the number we are dividing is large, this becomes very difficult. There are some divisibility rules which make this task much easier--these rules allow us to determine whether a number is divisible by another number without having to carry out the division.Divisibility by 1A number does not change when it is divided by 1. Therefore, every whole number is divisible by 1.Divisibility by 2, 4, and 8All even numbers are divisible by 2. Therefore, a number is divisible by 2 if it has a 0, 2, 4, 6, or 8 in the ones place. For example, 54 and 2,870 are divisible by 2, but 2,221 is not divisible by 2.A number is divisible by 4 if its last two digits are divisible by 4. For example, 780, 52, and 80,744 are divisible by 4, but 7,850 is not divisible by 4. To check whether a number is divisible by 4, just divide the last two digits of the number by 4. If the result is a whole number, then the original number is divisible by 4.A number is divisible by 8 if its last three digits are divisible by 8. For example, 880 and 905,256 are divisible by 8 but 74,513 is not divisible by 8. To check divisibility by 8, divide the last three digits of the number by 8. If the result is a whole number, then the original number is divisible by 8.Divisibility by 3, 6, and 9A number is divisible by 3 if its digits add up to a number divisible by 3. For example, 671,451 is divisible by 3 because 6 + 7 + 1 + 4 + 5 + 1 = 24 , and 24 is divisible by 3. 84,950 is not divisible by 3, because 8 + 4 + 9 + 5 + 0 = 26 , and 26 is not divisible by 3.A number is divisible by 6 if it is divisible by 2 and 3. In other words, a number is divisible by 6 if its digits add up to a number divisible by 3 and it ends with an even number. 671,451 (our previous example) is divisible by 3, but not by 2, because 1 is not an even number. Therefore, 671,451 is not divisible by 6. On the other hand, 789,312 is divisible by 6, because 7 + 8 + 9 + 3 + 1 + 2 = 30 , which is divisible by 3, and its last digit is 2, which is even.A number is divisible by 9 if its digits add up to a number divisible by 9. For example, 91,458 is divisible by 9 because 9 + 1 + 4 + 5 + 8 = 27 and 27 is divisible by 9. 18,453 is not divisible by 9 because 1 + 8 + 4 + 5 + 3 = 21 and 21 is not divisible by 9.Divisibility by 5A number is divisible by 5 if it ends in 0 or 5. For example, 875 and 600 are divisible by 5, but 76,508 is not divisible by 5.Divisibility by 10A number is divisible by 10 if it ends in 0. For example, 65,110 and 90 are divisible by 10, but 6,007 is not divisible by 10.Note: Because a number divided by itself always yields 1, a number is always divisible by itself. For example, 7 is divisible by 7 and 8,374 is divisible by 8,374.Note: No number is divisible by a number greater than itself.

Why a minute have sixty seconds?

The Sumerians' used sexagesimal (base 60) mathematics . This was because 60 is evenly divisible by the first few integers as well as a few others - unlike 10 which is divisible only by 1, 2, 5 and 10. The Babylonians adopted the Sumerian counting system and used that for their measurement of time.
