Consider celebrating #Metric Day on September 23 this year. It'll be the 25 anniversary of the NASA Mars Climate Orbiter slamming into the planet because one contractor (Lockheed Martin) disregarded NASA spec and calibrated a sensor in lbf instead of N.

This was a US $327.6 million project. This is the only image of Mars that the probe produced, taken at over 4 million kilometres away from the planet. The 576 non-zero pixels effectively cost $568,750 each.
