Google now includes a built-in BMI calculator in search results

A Google search for 'bmi calculator' now surfaces an interactive tool that lets users enter their weight and height to determine their BMI.

BMI results are displayed in a blue or green box - green for 'normal' results and blue for 'underweight' or 'overweight' results.

The calculator is sourced from the US National Institute of Health.
