Why Americans Still Use Fahrenheit Long After Everyone Else Switched to Celsius
Because change is hard, humans are stubborn and America is exceptional.
Virtually every country on earth aside from the United States measures temperature in Celsius. This makes sense; Celsius is a reasonable scale that assigns freezing and boiling points of water with round numbers, zero and 100. In Fahrenheit, those are, incomprehensibly, 32 and 212.
This isn’t just an aesthetic issue. America’s stubborn unwillingness to get rid of Fahrenheit temperatures is part of its generally dumb refusal to change over to the metric system, which has real-world consequences. One conversion error between US and metric measurements sent a $125 million NASA probe to its fiery death in Mars’ atmosphere.
Why does the United States have such an antiquated system of measurement? You can blame two of history’s all-time greatest villains: British colonialism and Congress.

“Motorists rebelled at the idea of highway signs in kilometers, weather watchers blanched at the notion of reading a forecast in Celsius, and consumers balked at the prospect of buying poultry by the kilogram,” Jason Zengerle writes in Mother Jones. Organized labor fought it as well, according to Zengerle, so workers wouldn’t have to retrain to learn the new measures.

The bizarre measurements commonly used in the US, including Fahrenheit, are bad for its scientific establishment, its kids, and probably its businesses.
Susannah Locke lays out the case for Celsius and the rest of the metric system very persuasively, but here’s a brief recap. The simpler metric scales make basic calculations easier and thus less error-prone. American companies incur extra costs by producing two sets of products, one for the US and one for the metric using world.
American parents and caregivers are more likely to screw up conversion rates when they give out medicine, sending some children, who are more susceptible to overdoses, to the hospital. Further, American students have to be trained on two sets of measurements, making basic science education even more difficult.
