>Note to downvoters: This is an objective answer to an objective question. It is not an opinion on the US's use of imperial units. It's an answer to a question that no one asked. The question was: >How is Fahrenheit more difficult to calculate with than Celsius, and what does it have to do with space probes? From the link you provided: >Specifically, software that calculated the total impulse produced by thruster firings produced results in pound-force seconds. The trajectory calculation software then used these results – expected to be in newton seconds – to update the predicted position of the spacecraft. It has nothing to do with Farenheit or Celsius. The error was with the representation of force, not temperature.
