Units explained
Square Furlong
A square furlong is an imperial unit of area equal to exactly 40,468.564 m², or 10 acres.
Derived by squaring the furlong (660 feet or 1/8 mile). The furlong itself comes from medieval English 'furrow long', the length of a plowed furrow.
Square furlongs are rarely used today. The unit appears occasionally in historical English farming records and in some horseracing contexts (though usually as length, not area).
Medieval English origin; standardized via the 1959 International Yard and Pound Agreement.
Square Pole
A square pole is identical to a square rod, equal to approximately 25.293 m². 'Pole' is a regional name used in some US and British contexts.
Identical to square rod and square perch; differs only in regional naming preference.
Square poles appear in some historical US land records, particularly in mid-Atlantic states with strong English colonial heritage.
Standardized via the 1959 International Yard and Pound Agreement.

Step-by-step: convert square furlongs to square poles
- Write down the value in square furlongs (fur²).
- Multiply that value by the factor 1600.
- The product is the equivalent value in square poles (pole²).
- To reverse, multiply the square pole value by 0.000625.
Worked examples
Example 1 — Convert 1 fur² to pole²:
1 × 1600 = 1600 pole²
Example 2 — Convert 100 fur² to pole²:
100 × 1600 = 160000 pole²
Real-world example — Endurance race distances
A 50-square furlong cycling or running race converts to a recognizable distance in square poles. Endurance athletes coming from a different measurement system use this conversion to compare training plans across regions.
50 fur² × 1600 = 80000 pole²
Real-world example — Maritime exclusion zone
A 200-square furlong exclusion zone (a common maritime boundary) converts to a different value in square poles that's useful when describing the same zone in everyday land-distance units.
200 fur² × 1600 = 320000 pole²
Real-world example — Coastal cruise distances
A 10-square furlong coastal sailing route converts to a different value in square poles — useful for cruise operators who switch between maritime, aviation, and road-distance units depending on the leg of the trip.
10 fur² × 1600 = 16000 pole²
