There is a conversion table between selected timezones (interesting for space fans) on my website, cf. URL
Metric vs. imperial units:
Inches (in), feet (ft), yards (yd), fps, psi, pounds (lbs) - those units are for us - non-Americans and non-British - no problems, because those units are exactly defined, with well known ratio to the metric units. But when someone uses "miles" without adjectivum, sometimes it is hard to recognize whether the author means statute miles (1.609 kilometers) or nautical miles (1.852 km). Difference 15 % !!!!!!!!
Similarly tons, short or long?
Gallons, UK or US?
Sorry, I prefer metric with simle decadic structure of units (of course, I am using this unit system for 62 years...).
