Ten. Two years of a predecessor's term, and two full terms of his own.
A United States President can serve at most two terms of four years each.
A term equals 4 years. A president can serve up to 2 terms meaning 8 years. For example. President Obama has been president for almost 4 years. His term is almost up. They will have an election in November and if President Obama wins, he will be president for four more years. Only 2 terms is the most for a president.
The term is 4 years . A president can serve at most two.
A person can be elected president at most two times.

Many believe that running the world's most powerful country makes the president the most powerful person in the world.
This is like a trick question. The maximum "number of years" one person can serve as President is unlimited. It is NOT 8 years. The 22nd Amendment states that no person may be "elected" more than twice. It says nothing about the number of years a person can serve. It also provides that no person who acted as President for more than 2 years during a term in which some other person was elected President may be elected more than 1 time. So, consider this situation: A vice president becomes president on the death of the president and serves exactly 2 years. Since it is not more than 2 years, he is able to be elected twice. That's 10 years. After that suppose he serves a vice president again and again succeeds to office on the death of the new president. Unlikely, yes, but theoretically it is not prohibited.
The current most powerful person in the world is Vladimir Putin, he is the president of Russia and he has maintained his power for 4 years due to him going in presidential place.
Technically, 12. In the most extreme of circumstances, a VP could become president for 4 years if the president were to be killed immediately after taking office. He/she could then be elected twice, equalling 8 years total as the elected president.
US presidents can be elected to no more than two terms of four years each. They can not serve for more than 10 years and so can not be elected for a second term if they have already served more than 2 years of another president's term. This limit is set by the 22nd amendment to the Constitution which was ratified March 27, 1951. Before that date, there were no limits on how many times a president might be re-elected.
The president
The president isn't the most powerful person in the world. God is. Presidents are the most powerful and important people in the USA.
