Examples
This years-to-centuries conversion works for any value, including decimals.
A century has 100 years. This stays the same in all common calendar use.
Divide the number of years by 100.
Example: 250 years ÷ 100 = 2.5 centuries.
Multiply the number of centuries by 100.
Example: 3.2 centuries × 100 = 320 years.
1 year equals 0.01 centuries (1 ÷ 100).
10 years equals 0.1 centuries (10 ÷ 100).
50 years equals 0.5 centuries (50 ÷ 100).
75 years equals 0.75 centuries (75 ÷ 100).
100 years equals 1 century.
125 years equals 1.25 centuries (125 ÷ 100).
150 years equals 1.5 centuries (150 ÷ 100).
200 years equals 2 centuries.
500 years equals 5 centuries.
1 century equals 100 years.
2 centuries equals 200 years.
5 centuries equals 500 years.
Yes. Centuries can be whole numbers or decimals.
0.25 centuries means 25 years, and 1.75 centuries means 175 years.
Use an ordinal number for the count of centuries. Examples: 1st century, 2nd century, 11th century, 21st century.
The 1st century runs from year 1 through year 100. There is no year 0 in the common AD/CE calendar.
The 20th century runs from 1901 through 2000.
The 21st century runs from 2001 through 2100.
The AD/CE calendar starts at year 1. Since there is no year 0, centuries count in 100-year blocks starting from year 1.
For years AD/CE, use this quick rule:
1900 is part of the 19th century. The 20th century begins in 1901.
2000 is part of the 20th century. The 21st century begins in 2001.
Yes, by definition a century equals 100 years. Calendar rules like leap years change the number of days, not the number of years.
A century has 10 decades, since each decade has 10 years.
A century has 1,200 months (100 years × 12 months).
It depends on leap years. A rough estimate is about 36,525 days (100 × 365.25). The exact count changes based on the years included.
Divide by 100 to get centuries. The whole number part is the centuries, and the remainder is the leftover years.
Example: 347 years = 3 centuries and 47 years.
