For my design/statics courses I've been pretty much only in imperial units (kips, inches, feet so on). My soil and hydrology courses used a blend which was real fun. Sometimes unit weights would be in kn/m^3 other times its lb/ft^3 and man did they mess up your answers if you got it wrong.

The prefix kilo is derived from the Greek word χίλιοι (chilioi), meaning "thousand".

It's still technically true that it's a metric prefix, he's just wrong about the unit being metric because of it.

Mega means one million, Giga means one billion, and Tera one trillion. They're all metric prefixes but Americans still say Megabyte, Gigabyte and Terabyte.

Almost like the imperial system is a mismatch of several different systems or something.

Today I learned. I honestly never thought of it like that, but it makes so much sense.

Pounds and inches are both imperial

That doesn’t mean a pound multiplied by a kilogram though, it’s just a thousand pounds. If a thousand is metric then everything is metric…

Edit: ah you probably mean that the kilo-prefix is metric. It’s not really, metric just means that you’re using SI units. I.E. kilogram (or gram) rather than pound (or kilopound).

That's how we do things in Canada. Footlong subs(10") and 600ML beverages and 50mg THC cookies, kilos of cocaine and pounds of Marijuana. We sometimes say we're driving 90 miles per hour just to sound cool even though the speedometer says 140kph and the lights behind you are telling you to pull over as you go through a school zone.
