Lifespan Comparison Calculator
Compare lifespans across different species. Convert between years, months, weeks, days, and see how your pet’s age compares to human years.
Step 1: Select Species
Understanding Lifespans
Different species age at different rates. For example, 1 dog year is approximately 7 human years for the first 2 years, then about 4 human years per year after that. This varies by breed and size.
Step 2: Comparison Options
Species Average Lifespans
Human: 79 years
Dog: 10-13 years (varies by breed)
Cat: 12-18 years
Rabbit: 8-12 years
Hamster: 2-3 years
Parrot: 50-80 years

Time Conversion Formulas
Basic Time Conversions
1 year = 12 months = 52 weeks = 365 days
1 month ≈ 4.33 weeks ≈ 30.44 days
1 week = 7 days = 168 hours
1 day = 24 hours = 1,440 minutes
Dog to Human Years
Small dogs: First year = 15 human years, Second year = 9, Each following year = 5
Medium dogs: First year = 15, Second year = 9, Each following year = 6
Large dogs: First year = 15, Second year = 9, Each following year = 7-8
Cat to Human Years
First year: 15 human years
Second year: +9 years (total 24)
Each following year: +4 human years
Rabbit to Human Years
First year: 20 human years
Each following year: +6 human years
