Standards on this website
Because this website is intended to address people from all countries, I have attempted to adapt the information to the relevant ISO standards. These include:
- Dates
- All dates will be presented in the extended standard date format as specified by ISO 8601 (YYYY-MM-DD).
- Sources
- All sources used will be listed according to ISO 690 where possible. It should be noted that due to the fact that many of the sources used are older than the ISO 690 standard, it isn't possible to present all the relevant information for each source, but enough information should be presented to make the source identifiable.
- Measurements and numbers
- All measurements and numbers will follow ISO 31. For numbers, this means that a space will be used as the thousands seperator, and a comma will be used as the decimal seperator. For measurements, this means that the metric system will be used. Where the information was originally available using other systems, such as for the US tanks, the original measurement will be given in parantheses. The following conversion ratios are used, rounded to two decimals:
- 1 pound (lb) = 0,45359237 kilogram (kg)
- 1 inch (in) = 2,54 centimetres (cm)
- 1 foot (ft) = 0,3048 metre (m)
- 1 mile = 1,609344 kilometre (km)
- 1 US gallon (US gal) = 3,7854117840045967 litre (l)
- 1 mile per hour (mph) = 1,609344 kilometres per hour (km/h)
- 1 imperial horse power = 1,01387119964513876 metric horse powers (hp)
- 1 pound feet (lb-ft) = 0,138254954376 kilogram metres
- 1 pound per square inch (lb/in2) = 0,070306957963915927831855663711327 kilograms per square centimetre (kg/cm2)
