Hi All

Just found this spreadsheet this week. really is great...
Im using it to try to work out a gearbox / reduction (transfer) ratio
on my land rover expedition truck which has been converted to a diesel
engine.

One thing which Ive noticed may just be something Im doing but the bit
on the input sheet that works out the RPM ina certain gear at a certain
speed seems to work fine in KPH but not in MPH? trying to find a good
ratio to cruise at 2500rpm in top gear (can see it on the gearing graph
anyway but would be good to figure out what Im doing on the input page)

Cheers
Ben
