Estimate how quickly a car reaches 60 mph from a standstill using its horsepower and curb weight. Acceleration is driven mostly by the power to weight ratio, so this estimator uses a widely cited empirical model that ties the 0 to 60 time to weight divided by power. Enter the horsepower and the weight in pounds and you get an approximate time along with the power to weight ratio in horsepower per ton. Real world times depend on traction, gearing, drivetrain, and launch technique, so treat the result as a ballpark for comparing cars rather than a guaranteed figure. It is a fun and useful way to see why shedding weight can matter as much as adding power, and why light cars often feel faster than the numbers suggest.

It uses a power to weight model, since acceleration depends on how much horsepower moves each unit of vehicle weight.
It is horsepower divided by weight, a key predictor of acceleration that the tool reports alongside the estimated time.
It is an approximation. Real 0 to 60 times also depend on traction, gearing, and driveline, so treat it as a ballpark.
