While home insulation remains one of its most common applications, the name itself has become a generic term for any material containing thin fibers of glass formed into a woven layer or used as reinforcement. The glass in fiberglass is the same basic substance used in windows and glassware. Molten glass is extruded through ultra fine openings measured in microns, resulting in thread-like formations which can be woven together to form a rough cloth or patch.
The answer is 100. We assume you are converting between decade and millennium. You can view more details on each measurement unit: decade or millennium. The SI base unit for time is the second. 1 second is equal to 3.17097919838E-9 decade, or 3.17097919838E-11 millennium. Note that rounding errors may occur, so always check the results.
Therefore, January 1, year 1, is defined to be the start of the 1st century and the start of the 1st Millennium. Because one Millennium is 1000 years, the first Millennium ends with year 1000. The next (2nd) Millennium starts 1000 years after the first, that is in year 1+1000 = 1001. And the 3rd one starts 1000 years later than the 2nd: 1001+1000 = 2001. The same procedure could be followed for centuries. See the tables below for more information.
