The total mass of CO2 is about 3 trillion tonnes (3 teratonnes). (That's a 3 with 12 zeros, 3,000,000,000,000 tonnes.) C12 + 2O16 means 12 parts in 32, by weight, are carbon. 3/8ths. So, 1-1/8 teratonnes. That is about 2.5 quadrillion pounds, or 1.125 quadrillion kg.
We'd probably use the term 1 gigayear to mean 1 billion years (in the U.S.). The prefix "giga" means 1,000,000,000 or, if you prefer, 106 units of something. The gigayear is a billion years, just the the gigaHertz is a billion Hertz (or cycles per second). Also note that we use a "big" G to represent giga. A Gyear is a gigayear or a billion years.Many consider an Eon to be a billion years
The three categories for forecasting time horizons are short-term (up to 1 year), medium-term (1-3 years), and long-term (beyond 3 years). Short-term forecasts are used for operational planning, medium-term forecasts for tactical planning, and long-term forecasts for strategic planning. Each horizon has different data requirements and accuracy levels.
There are 1 trillion years in 1 trillion years!
1 Parsec = 3.26163626 light years
31,709,792
The common term for this value is a quadrillion.
1 trillion years
There are 31,540,000,000,000,000 (31 quadrillion, 540 trillion) seconds in 1 billion years.
One quadrillion
1 quadrillion in Scientific Notation = 1 x 1015
One quadrillion
1,000,000,000,000,000 = 1 quadrillion 1,000,000,000 = 1quadrillion / 1 million
1 quadrillion would be 1000 million million.
quadrillion?
1,000 trillions equals 1 quadrillion
109 = 1 billion. 1012 = 1 trillion. 1015 = 1 quadrillion. Therefore, 1 quadrillion = 1,000 trillion = 1,000,000 billion. So, your statement is wrong. One hundred quadrillion = 1 thousand trillion.
