How this is calculated

Result = Value × (metres per 'from' unit) ÷ (metres per 'to' unit)

1 inch
0.0254 m exactly (so 1 foot = 0.3048 m, 1 mile = 1,609.344 m)
1 nautical mile
1,852 m exactly

Every unit is defined as an exact number of metres — since the 1959 international yard and pound agreement, an inch is exactly 2.54 cm — so conversions are exact; results are shown to 10 significant figures so very small or very large values keep their precision.
