Rat years to human years

rat years to human years

Do you want to convert rat age to human years? Estimations show that in adulthood, each rat's year equals approximately 30 human years, and each month - 2,5 human years. For example:

  • 1 year old rat is 30 years old in human years
  • 3 years old rat is 90 years old in human years

As for rat pups (under 1 year old), their human age is calculated differently. Due to a short lifespan, young rats develop very quickly compared to human kids. So if you think that a 6-month-old rat is 15 in human years, your calculations are incorrect.
