Units explained
Hectare
A hectare is a metric unit of area equal to 10,000 square meters, or one square hectometer. It is the most widely used metric unit for land measurement worldwide.
Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.
Hectares are the standard unit for agricultural land measurement worldwide except in the US (which uses acres). 1 hectare equals 2.47105 acres. In India, hectares are used in modern agricultural census and land records alongside traditional regional units.
Adopted in France in 1795; standardized internationally through the SI system.
Section
A section is a unit of area used in the US Public Land Survey System, equal to 1 square mile (640 acres or approximately 2.59 km²).
Defined by the Land Ordinance of 1785 as 1/36 of a township. Sections are numbered 1-36 within each township.
Sections are the fundamental unit of US public land records in PLSS states (essentially the central and western US). Property descriptions like 'NE quarter of section 14, township 3 north, range 2 east' use this system.
Defined by the US Land Ordinance of 1785.

Worked examples
Example 1 — Convert 1 ha to sec:
1 × 0.0038610216 = 0.0038610216 sec
Example 2 — Convert 100 ha to sec:
100 × 0.0038610216 = 0.3861021585 sec
Real-world example — Road-sign distances across systems
A 100-hectare road sign converts cleanly into sections — exactly the conversion drivers planning trips abroad rely on when reading road signs in a different measurement system.
100 ha × 0.0038610216 = 0.3861021585 sec
Real-world example — Endurance race distances
A 50-hectare cycling or running race converts to a recognizable distance in sections. Endurance athletes coming from a different measurement system use this conversion to compare training plans across regions.
50 ha × 0.0038610216 = 0.1930510793 sec
Real-world example — Maritime exclusion zone
A 200-hectare exclusion zone (a common maritime boundary) converts to a different value in sections that's useful when describing the same zone in everyday land-distance units.
200 ha × 0.0038610216 = 0.7722043171 sec
