We have different metrics internationally for length/distance, weights, temperature, etc. Why, as far as I know, is there only hours/minutes/seconds for the entire world? Not that I’m complaining, the alternative would be a huge pain in the a**, but I’m curious how that happened over time (sorry about the pun). TIA!
In: Physics
Mostly because of European expansion. Western European nations were very, very interconnected, and these nations, especially England, Portugal, Spain and France set up colonies all over the planet, bringing with them their units of measurement. When modern infrastructure was being set up, such as the telephone system and the Internet, it was largely done by these countries or their colonies, so this became the standard.
Other countries and cultures can and do still use different time measurements. For instance, according to the Hebrew calendar, it’s the year 5784
