Comment False precision fallacy (Score 1) 199
Fahrenheit has smaller degrees so you never need to involve a decimal place.
Well actually, consumer-grade thermometers that are actually accurate within ±1F (or better) are far and few between. Fahrenheit is de facto false precision masquerading as a unit.
Combined with my other metrology pet peeve; digital meters showing more significant figures than their accuracy warrants for, those chinesium digital wall thermometers really grind my gears: "No, it's not 68.4F - it merely means it's most likely somewhere between 66.6 and 70.2F - you might as well roll a dice, you self-deluded bozo!"
