Subject: 14) How do I convert from mph to knots (or m/s), from inches of mercury to mb (or hPa), or convert degrees of latitude to miles (or kilometers) ?

For winds:

1 mile per hour = 0.864 nautical miles per hour (knots)
1 mile per hour = 1.609 kilometers per hour
1 mile per hour = 0.4470 meter per second
1 knot = 1.853 kilometers per hour
1 knot = 0.5148 meter per second
1 meter per second = 3.6 kilometers per hour

For pressures:

1 inch of mercury = 25.4 mm of mercury = 33.86 millibars
= 33.86 hectoPascals

For distances:

1 foot = 0.3048 meter
1 nautical mile = 1.1515 statute miles = 1.853 kilometers
1° latitude = 69.057 statute miles = 59.969 nautical miles
= 111.137 kilometers
For longitude the conversion is the same as latitude except the value is multiplied by the cosine of the latitude.
