If you are talking about an E6B, you follow the same rules for your result as you followed for your inputs. If you used a factor of 10 for your inputs, you use a factor of 10 for your results. If all else fails, you use the common sense rule. For your particular calculations, does 241 make sense? Or, does 24.1 make sense?
