Should I call it an article? Yes, but it's more of outlines. It is outlined to choose what you're seeking answer. Nevertheless, you ought to know the basics of time conversion, and here they are:

60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
7 days = 1 week
52 weeks = 1 year
10 years = 1 decade
10 decades = 1 century = 100 years
100 decades = 1 millennium = 1000 years

I know you must have observed why 'month' was omitted. It was, because it varies; it ranges from 28 days to 31 days. (A month is equal to 4 weeks, 4 weeks and one day, 4 weeks and two days, or 4 weeks and three days.). There are 86,400 seconds in a day.

Check out the mathematical expression:

1 minute = 60 seconds
60 minutes = 60 seconds x 60 seconds = 3600 seconds.
60 minutes = 1 hour
60 minutes = 3600 seconds.
So, 3600 seconds = 1 hour
There are 24 hours in one day.
1 hour = 3600 seconds
24 hours = 3600 x 24 = 86,400 seconds.

Pore over this outline:

•    1 day = 84,600 seconds
•    7 days (1 week) = 604,800 seconds
•    14 days (2 weeks or a fortnight) = 1,210,000 seconds.
•    28 days = 2,419,000 seconds
•    29 days = 2,506,000 seconds
•    30 days = 2,592,000 seconds
•    31 days = 2,678,000 seconds
•    5days - 100 days
•    5 days = 432,000 seconds
•    10 days = 864,000 seconds
•    15 days = 1,296,000 seconds
•    20 days = 1,728,000 seconds
•    25 days = 2,160,000 seconds
•    30 days = 2,592,000 seconds
•    35 days = 3,024,000 seconds
•    40 days = 3,456,000 seconds
•    45 days = 3,888,000 seconds
•    50 days = 4,320,000 seconds
•    55 days = 4,752,00 seconds
•    60 days = 5,184,000 seconds
•    65 days = 5,616,000 seconds
•    70 days = 6,048,000 seconds
•    75 days = 6,134,400 seconds
•    80 days = 6,912,000 seconds
•    85 days = 7,344,000 seconds
•    90 days = 7,776,000 seconds
•    95 days = 8,208,000 seconds
•    100 days = 8,640,000 seconds

KEY POINTS

Millennium = 1000 years
Century = 100 years
Decade = 10 years
