What is a digital speedometer?

I know that cars have a round thing in them with an arrow pointing at the current speed, but what makes it digital?

@vaporeon_ there is a digital screen on the dashboard next to the speedometer dial. i would like for it to have my speed displayed there with numbers, because i find it easier to read at a glance than trying to read the dial

i can read the dial but i'd like knowing my speed to be as easy as possible

@monorail Oh! Thanks for explaining, I wasn't aware that that's an option, it's rare to see cars with a digital screen in them

@vaporeon_ that's interesting, where i am cars are moving so much stuff to digital screens that people are trying to get them to stop lmao

(digital screen on the dash: good imo! moving physical controls to touchscreens: bad)

@vaporeon_

@monorail Sorry for the stupid question, but what's the other indicator for? The one that goes from 0 to 8? I think I've seen it before, but as I said, I don't know how to drive a car...

@vaporeon_ @monorail it measures how many revolutions purr minute (RPM) the motor is going through, in units of thousands

apparently the term fur this kind of gague is “tachometer”. i may have known that years ago

@aescling @vaporeon_ @monorail 🌮

@onfy @aescling @monorail Tacho-meter (ch sound, I assume it's like Russian х or Greek χ? correct me if that's not the case in English, I thought it's a Greek-derived word, though), not Taco-meter (c pronounced like k)

@vaporeon_ @onfy @monorail while the greek letter chi is a velar(?) fricative and not a stop, when transliterated into english we just use a velar stop

the taco reading doesn’t work though because the stress is on the second syllable and the weak a gets rendered as schwa

@aescling @vaporeon_ @monorail i've always heard it pronounced "taco meter"?

@onfy @vaporeon_ @monorail i cannot find a dictionary attesting such to such a purronouciation but maybe they need to be updated
