1. To keep with the science-y feel of the site, metric measurements are standard on all articles. However, in some articles-mostly older ones-there are Imperial equivalents provided in parenthesis, and occasionally it's the other way around. Is this acceptable?
2. What date format should be used on the articles? DD/MM/YY, MM/DD/YY, or YYYY/MM/DD? Or are any of the three acceptable?
