On Sep. 23, 1999, $125,000,000 Mars Climate Orbiter entered Mar's atmosphere 100 km lower than planned and was destroyed by heat.
Reason?
NASA engineer mistook conversion factor as 1 lb = 1 Newton (Reference: https://en.wikipedia.org/wiki/Mars_Climate_Orbiter)
"lb" is English unit of force. 1 lb = 4.45 N
Force = Mass x Acceleration
= 0.454 kg * 9.81 m/s^2
= 4.45 kg.m/s^2
= 4.45 N ( 1 N = 1 kg.m/s^2)
This $125 million catastrophic event could have been averted with a more careful dimensional analysis and unit conversion.
Can you imagine yourself to be that NASA engineer? It is a terrifying thought!
You can avoid such costly engineering unit conversion mistakes by using Enverter.
Enverter is a dimensional analysis and unit conversion software for engineering and scientific calculations. (Curious about what is Dimensional Analysis? This video migh thelp: https://www.khanacademy.org/math/algebra/x2f8bb11595b61c86:working-
