Too bad we cannot estimate the cost of not being metric that includes also the money and trouble spent on fixing errors caused by unit mix-ups.
Quote: The researchers originally reported that a set of 14 PAHs had total concentrations of 330, 240, and 210 ng/m3 for the three groups, respectively. But they later discovered that they had mistakenly used a value of the ideal gas constant with incorrect units in their calculations to determine the air concentrations of PAHs and to adjust them for sampling temperature, Anderson explains. This error invalidated the original results.
