The Navy Physical Readiness Test (PRT) calculator is a tool used to assess the physical fitness of sailors in the U.S. Navy. This calculator evaluates navy prt calculator performance based on the three main components of the PRT: the 1.5-mile run, curl-ups, and push-ups. For the run, sailors' times are converted into a score, while the number of curl-ups and push-ups completed in two minutes is also scored.
