Map Scales 
In all maps used in France the scale is represented by a
fraction e.g. 1/5000, 1/10000 etc.
To convert a Representative Fraction into a definite
statement, divide 63,360 (inches in mile) by denominator of R.F.
Contours, Vertical Interval, Horizontal Equivalent.
True North, Magnetic North, Magnetic Variation
Maps used in France.
1/5000 Used for Contact Patrol Work.
1/10,000 For Trench Work
1/20,000 For Artillery Map.
1/40,000 Short Reconnaissance
1/100,000}  Long Reconnaissance
