How to Use This Calculator
  1. Enter the starting temperature when cooling began (°F) and the current measured temperature.
  2. Enter elapsed time in minutes since cooling started.
  3. Select the cooling method (FDA 2-Stage: 135→70→41 °F, or one-stage).
  4. The calculator shows cooling rate, projected total time, stage 1 compliance status, overall compliance, minutes remaining, and required rate to stay compliant.
  5. If cooling rate is insufficient, use an ice bath, blast chiller, or smaller portion containers to accelerate the process.
