Hey Crash One, I think you meant 'feet' not 'yards'.

Which is a nice segue into an issue which has bedeviled my business, oil exploration. Depending where I am in the world, the units can be SI, or Imperial or a mixture! Then on top of that, historical documents can be in different units.

Some time ago, a colleague was having a problem with data from a document showing the depths to geological formations ("tops") in a exploration well and asked me to take a look. The numbers did not pass the BPF's TLAR test.

"Are these tops about three times bigger than you were expecting?"
"Yes. Why?"
"You've got a feet to metres problem."
