To convert centuries to decades, use this simple rule:

Example:
This centuries to decades conversion works for whole numbers and decimals. For example, 1.5 centuries = 15 decades.
There are 10 decades in 1 century. A decade is 10 years, and a century is 100 years. Since 100 ÷ 10 = 10, one century equals ten decades.
Multiply the number of centuries by 10.
Example: 3 centuries × 10 = 30 decades.
Use this simple formula:
Decades = Centuries × 10
2 centuries equal 20 decades.
Calculation: 2 × 10 = 20.
Half a century is 0.5 centuries, which equals 5 decades.
Calculation: 0.5 × 10 = 5.
A quarter century is 0.25 centuries, which equals 2.5 decades.
Calculation: 0.25 × 10 = 2.5.
Yes. If the centuries value includes a fraction or decimal, the decades result can also be a decimal.
Example: 1.2 centuries = 12 decades.
0.1 century equals 1 decade.
Calculation: 0.1 × 10 = 1.
A century is defined as a period of 100 years. The word comes from a Latin root that means “hundred.”
A decade is 10 years. A century is 100 years. A century is 10 times longer than a decade.
Not always. Years 1900 to 1999 are in the 20th century. Years 2000 to 2099 are in the 21st century. Century counting starts at year 1, not year 0.
A new century starts on years ending in 01.
For example, the 21st century began on January 1, 2001, and will end on December 31, 2100.
5 centuries equal 50 decades.
Calculation: 5 × 10 = 50.
Divide the number of decades by 10.
Example: 45 decades ÷ 10 = 4.5 centuries.
Use place value. Multiplying by 10 moves the decimal one place to the right.
Example: 2.7 centuries becomes 27 decades.
