They go different directions so that if you're measuring only one side of something (like a wall) and spin the ruler to switch from one the other, they go in the same direction.*grabs ruler*
Can someone tell me why inches and centimeters don't go the same direction on a ruler? If zero were on the same end for both, it would be so much easier to compare.
*disappointed with the ruler, does the required math*
Hmm. I don't think centimeters could be correct either. Perhaps the "scientific research" was in the form of a survey. If that's the case, inches would make sense.
Looking at the original map, and it's accompanying data, it is given in cm. https://www.targetmap.com/viewer.aspx?reportId=3073
