The method, explained
Converted area = input × square meters per source unit ÷ square meters per target unit. One hectare is 10,000 m²; one international acre is 4,046.8564224 m².
One acre equals 4,046.8564224 square meters. One hectare equals 0.01 square kilometers.
What to keep in mind
Area factors are squared length factors. The acre and square foot use international definitions, not historical survey-unit variants.
Common questions
Can I use a length conversion factor directly?
