Today I had my annual physical examination. The Digital Display of the electronic device for measuring my Body Mass was set at *kilograms*.
The Telescoping Scale for measuring my height was engraved mechanically in *centimeters*. Of course, my height was then easily expressed in meters for calculating my Body Mass Index. BMI = mass (kg)/(height (m)^2) Unfortunately, I must now carry a Holter Heart Monitor for 24 hours to record a continuous digital Electrocardiogram of my heart rate, rhythm and patterns which showed some signs of irregularity.
