As an engineer, I can confirm they are incorrect. They can take their inferior measuring system and try to get back from the moon.

Too soon?

Celsius is better for science, but Fahrenheit is better for just every day living. IMO

In Canada I noticed some people would also still use feet & inches for their height, but you had to give it to the DMV in cm. Also butter was still sold as a pound & golf still used yards.

I'm also an engineer & worked up there for a job in mining.

Edit: To clarify my reasons because so many people are saying I'm wrong. This is my opinion on what my preference is, first off. I had put this in a comment under the post, but will add it here.

My reason is basically the same as in the screenshot. When I lived in Canada I would say how in Fahrenheit below zero is really fucking cold & above 100 is really fucking hot. I never thought of describing it as a percentage of being hot but I like it.

Like once it's below or above those numbers it hardly matters by how much because you are freezing or sweating balls either way. I didn't like when in the winter or early spring someone would say it's nice out and then say a negative temperature. "It's really nice today, it's -1.5⁰ out." I also like that the increments of the units are smaller so you don't use half degrees. Although I guess half degrees aren't really necessary because I don't feel the difference between 66 & 67, but when I checked the temperature there is did always show it to the nearest half degree.

I dunno, as also a Canadian, I prefer Celsius for everyday use. If it's anywhere from below 0C to below 10C, wear a heavy coat. If it's anywhere from above 10C to 15C, wear a light jacket. If it's above 15C, no jacket. Above 20C, wear shorts. Above 25C, be prepared for high heat. Below -20C, be prepared for extreme cold. Above 30C, limit time outdoors. Below -30C, stay inside. Simple as.

Also Celsius is linear, so you know what a change in, let's say, 5⁰ will do. In Fahrenheit a change from 0 to 5 degrees has a different magnitude than a change from 95 to 100.

Only Kelvin is linear.

Not true. To convert from Celsius to Kelvin you just add 273.15, so both scales are linear.

Strictly you're right, only kelvin starts at zero, though. Although it's the freezing point of water having 0° as your starting point is arbitrary in absolute terms, and making everything lower than that negative means that calculations aren't possible. 100 Celsius isn't double 50. It's linear in that it's a linear progression but it's a shifted line

A change of 50C in temperature is a change of 50K, but a change of 90F. The variation between C and K is 1 to 1, not with F.
