BMI, running pace, and target heart-rate calculators — quick screening estimates for everyday fitness and wellness.

• BMI Calculator

  Calculate Body Mass Index (BMI) from weight and height in metric or imperial units. See your WHO category and a step-by-step breakdown of the formula.

• Pace Calculator

  Calculate running pace and speed from distance and time. Leave one field blank and solve for it — pace in minutes per km or mile, speed in km/h or mph.

• Target Heart Rate Calculator

  Calculate your maximum heart rate (Fox or Tanaka formula) and five target training zones, using plain percent-of-max or the more personalized Karvonen method.
