In some countries, blood sugar level is measured in mg/dL. I believe that the use of dL rather than litres or mL is to avoid using decimal separators. A blood level are typically in the range of 75 to 150 mg/dL. This could be written as 0.75 to 1.5 mg/mL or 750 to 1500 mg/L. The first of these has decimal separators and the second has a “surplus” zeros. The same argument applies to the use of centimetres rather than metres for people’s heights.

Anyway, metric includes multiples and submultiples of the main unit. John Altounji One size does not fit all.

Every card I have ever seen renders height in centimeters only. I have never seen an ID card rendering height in meters (for example 1.81 meters; I always say 181 centimeters, which is my height). The photo attached shows the ID card of this captured Jordanian soldier as 178 and does not even bother mentioning that those are centimeters, since it is common knowledge. When considering which unit to use for any purpose, it is preferable, in my opinion, to avoid having to use a decimal. It just makes your number a lot cleaner. Also, take notice of the date format and the absence of how heavy one is. Any thoughts? David Pearl www.MetricPioneer.com 503-428-4917
