You probably want to get units correct too. Say Newtons vs Kelvins vs Amperes... Still able to estimate right size is in general skill that should be taught.
I don’t even think they taught that much, I’m pretty sure I learnt about Newtons in mechanics (A-level maths course), Kelvin from reading Wikipedia and Amps I think I knew because my dad worked in motor repairs. My knowledge is old now, pre-2008 before the Gove reforms.
