He was referring to our &#x27;schizophrenic&#x27; use of it. It&#x27;s used differently among generations. Older people use purely imperial, whereas young people use a confusing mixture. For example, I measure long distances in miles, but short distances in meters and centimeters! I think of weights and volumes in a metric way, except when talking about the weight of a person, when I use stone (not pounds, mind you).<p>I might be an extreme example, but most people use an imperial-metric melange of some kind.
