Yes, England primarily uses the metric system for weights and measures. However, in some cases, imperial units are still used alongside metric units.
Both systems are in use in England (and indeed in Great Britain as a whole). In the past originally only the armed forces used the 24 hour system but now the whole population is aware of it. Some people use the 24 hour clock system and some just use the am/pm system, most people however are adept at using both systems.
England is a country and is unable to use a computer. The people who live in England use a variety of computers including Apple Macintosh and various computers, including Macs, running the Windows operating system. (See links below)
The significant change in weights and measures in England occurred with the Weights and Measures Act of 1824, which established a system of standard units based on the metric system. This act aimed to unify the various local systems of measurement that were in use at the time. The metric system was officially adopted in England in the 20th century, with further legislation in the 1960s and 1970s promoting its use alongside traditional units.
