I realize this tool was made by people who use the metric system but for us in the states this is useless overall great tool but hard too closely watch a possible mass air flow issue with a scale this broad maybe addressed in future updates thanks
I agree strongly with jon38. Grams/sec would work much better as a more detailed reading. Making all the scales independantly selectable would add much better personal customization, not just English OR Metric. Similar to what Snap-on does on their scan tools.
