Teachers really out here choosing violence by using kmh⁻¹ (kilometers per hour inverse) instead of the perfectly functional ms⁻¹ (meters per second). Because nothing says "I care about your education" quite like forcing students to do unnecessary unit conversions that add exactly zero pedagogical value. It's like watching someone meticulously arrange beakers in alphabetical order while the lab is on fire.
For context: kmh⁻¹ is technically just 1/(km/h), which is... hours per kilometer? So you're measuring how many hours it takes to travel one kilometer. It's the speed unit equivalent of measuring your height in inverse meters. Technically correct, maximally cursed. Meanwhile ms⁻¹ is the standard SI unit that every physics problem actually wants.
The Breaking Bad meme format captures that exact moment of malicious precision—carefully, deliberately making things harder than they need to be. Chemistry teacher energy, honestly.
