Same with 6" instead of 150mm. But if I'm actually geetting a tape out to measure it - mm all the way.Volumes I tend to do in litres or buckets as most buckets are about 10 litres which isn't that far off a gallon as a rough estimate anyway. I also have a mental picture of 25litres (small oil drum) 200litres (big oil drum) and a tonne is a cubic metre of water.Rig side of the oil industry makes no sense to me at all.
