Yeah if the person at the top of the image had any sense, they'd criticise us for this.
Road markings are in miles. Satnav units/apps usually either use imperial or metric, so they'll tell you to turn in X yards...but nobody has any idea how far a yard is, we usually use meters. Except for people's height where we use feet and inches.
Everything in shops is measured in grams or ml. Except for milk which is measured in pints.
Smaller measurements are done in cm but if you're approximating you'll use inches.
We're weird. In a way America kind of makes more sense by only using imperial, although ofc metric is better. But at least they only use one standard
