A period of one hundred thousand years is called a "hectocentury." In geological and paleoclimatic contexts, this timescale is often relevant for studying climate cycles and major geological events.
That's called a millenium.
One hundred thousand million years is called one hundred billion years. In scientific terms, this is often expressed as 100 gigayears (Gyr), where "giga" denotes a factor of one billion. This timescale is often used in cosmology and geology to discuss the age of the universe or the Earth.
A period of 100 years is a century
One thousand, nine hundred ninety-five years.
Ten thousand years is called a "decamillennium." The term "millennium" refers to a period of one thousand years, so ten of these periods constitute a decamillennium. In broader historical contexts, such long time spans can also be referred to in terms of epochs or eras, depending on the specific focus of study.

A period of ten thousand years is called a decamillennium. The prefix "deca-" denotes ten, and "millennium" refers to a period of one thousand years. Therefore, a decamillennium is a unit of time equal to ten millennia or ten thousand years.
One thousand years is a millennium, from the Latin "mille" for "thousand". One hundred years is a century, from the Latin "centum" for "hundred".
A period of 600 years is often referred to as a sexcentenary.
There are a hundred years in a century.
A thousand million years equals 1 billion years.
