Convert Human Age to Dog Years
A fast, accurate, and privacy-first calculator that converts human age into equivalent dog years using a modern veterinary-informed formula. All calculations run locally in your browser - no tracking, no data collection, and zero server processing.
Age Conversion Tool
About This Tool
This converter uses a modern age-equivalency model rather than the outdated "multiply by 7" rule. Research shows dogs mature rapidly in early years and age more slowly afterward. This tool applies that nonlinear aging pattern to provide a more realistic comparison between human and canine life stages.

Fun Fact
Dogs age extremely quickly in their first two years. By age two, most dogs are biologically similar to humans in their early twenties - which explains why puppies mature so fast compared to humans.
Historical Context
The "1 dog year equals 7 human years" rule dates back to the early 20th century as a rough lifespan comparison. Modern veterinary science, however, has shown that canine aging follows a nonlinear biological progression influenced by breed, size, and genetics. This updated model reflects current scientific understanding.
