Do Americans "largely use units like inches, yards, pounds and gallons?”. Certainly, but it’s the media that demotes or removes metric units in their publications. So who does use metric? If you work on cars yourself you use millimeters, all nuts and bolts are metric. All vehicle manuals have the torque in Newton meters. Which leads to the question, why do mechanics have to purchase inch and metric wrenches and sockets? They must not realize all nuts and bolts are metric! US vehicles prior to 1975 are not metric, but that’s almost 50 years ago, how many people work on US made vehicles over 50 years old? If you take your car to a garage they use millimeter wrenches and sockets. All cars built in the USA and overseas are designed and built to millimeter specifications with metric nuts and bolts. This includes GM, Ford, Chrysler (Stellanis), Tesla, etc. If you are a farmer, or work on construction equipment and own a John Deere or Caterpillar you use millimetres, all nuts and bolts on John Deere and Caterpillar are metric. Even the steel in Caterpillar equipment is purchased in hard millimeter dimensions. They have to sell these products worldwide so metric is standard. If you’re a doctor or work in hospital you use Celsius, kilograms, grams, milligrams etc. It’s necessary to know your mass in kilograms to calculate the drug dose, converting errors would double or halve the required dose. All newborn babies in the USA are weighed in grams which is converted to pounds and ounces for the parents. If you are an Air traffic controller you use Celsius even in the USA because all airports give the air temperature in Celsius (listen +1 703 661 2990). All upper air temperature and pressure is in Celsius and kilopascals. If you are a Pilot in the USA all airport temperature and dew point temperature are in Celsius, all aircraft performance data is in Celsius. If you fly outside the USA you will then have to deal with visibility in metres and pressure in hectopascals. If you work for the National Weather Service you are exposed to metric units all day every day. The pressure inside hurricanes is measured in mb by the NWS which is millibars, a deprecated unit known worldwide as a hectopascal. If you are a scientist you only use metric. The news media will change it to what they think the public wants. People who work at JPL and NASA use metric which are changed to US customary for public consumption. If you work at Space X all units used even for launch data, are all metric. If you are an architect or civil engineer you will need to know metric if you want to work outside the USA. I could go on but it’s a sizable percentage of the US population. So it appears the only people in the USA not using metric is the US news media. One reason I subscribe to Deutsche Welle News in English instead of the NY Times or Washington Post. I cancelled my National Geographic subscription in 1990 because they cancelled their policy of including metric units.
