Every food label, with very few exceptions, lists the contents in either grams or milliliters, in addition to ounces or fluid ounces. Every thermometer I’ve ever seen has both Fahrenheit and Celsius scales. We buy electricity in watts with metric currency. We measure the light output in lumens, and the common lightbulb sizes are measured in millimeters, but the wires that carry the electricity are measured by AWG. The parts on my bicycle and car all use metric measurements, except for tires. Tires are an unholy abomination with section width given in millimeters, the cross-section in a unitless ratio, and the rim diameter given in inches.

Meh, what’re you gonna do? We switched to, or adopted, SI and metric where it made sense, but we have a lot of legacy systems.
