The expected rabbit lifespan is between 9 and 12 years. The world's oldest though was said to have reached the ripe old age of 18.
Rabbit years, based on dog years, aren't a scientific thing in that they are only ways to loosely explain age in the animals. There is not an officially recognised time span that is known as a rabbit year.
So to calculate a rabbit year, or a dog year, or any other animal year, the most commonly used method is to express the equivalent portion of an animal's lifetime, as a calendar year would be for a human being.
So an average mongrel dog lives for 13 years. An average human being in the USA lives to 78. So for every six years an American person lives, his dog lives one dog year. Therefore a five-year-old dog is 30 in dog years.
As for your rabbit, the average age of 10.5 means that for every year an American person lives, the rabbit lives 7.4 rabbit years. Therefore a five-year-old (in human years) rabbit is 37-years-old in rabbit years.
So to calculate how old your rabbit is in rabbit years, multiple his human years age by 7.4.
As previously mentioned though, this is not scientific method. This is because there are so many factors that cannot be standardised. For example, Germans live longer on average than Americans. So if you were doing this calculation in Germany, the rabbit years would be longer because more time passes in the equivalent human lifespan.
Also, the breed of animal makes a difference. A mongrel dog lives 13 years on average but a Scottish Terrier's average innings is 10. Average age in rabbits would also be affected by their gene pool.
