While am too lazy too look it up, I believe you. Why though, do all interstate highways and other federally funded roadways have their signage in MPH and feet? Same for US air travel (Federally regulated / subsidised) and weather stations like NWS (who I know does use metric, just not all the time)?
Do they use metric for these things and then just post signage in non-metric for the public to use because we’re too fragile for a sensible measuring system ?
The US federal government switched to metric decades ago.
So, nobody had to measure in inches or Fahrenheit. And if they got funding from the federal level, they were required to do it in metric.
If some research also included Fahrenheit or inches, that person was just being voluntarily weird
