Kilometer Square (abbreviation: km2): is the SI derived unit of area. It is the area of a square whose sides measure exactly one kilometre. The square metre is derived from the SI base unit of the metre, which itself is the length of the path travelled by light in absolute vacuum within time interval of 1/299,792,458 * 1000 of a second.
Foot Square (abbreviations: ft2, or sf, or sq ft): (plural square feet) is an imperial unit and U.S. customary unit (non-SI, non-metric) of area.
How to Convert Kilometers Square to Feet Square
Example: How many feet square are equivalent to 80.49 kilometers square?
As;
1 kilometers square = 10763910.416624 feet square
80.49 kilometers square = Y feet square
Assuming Y is the answer, and by criss-cross principle;
Y equals 80.49 times 10763910.416624 over 1
(i.e.) Y = 80.49 * 10763910.416624 / 1 = 866387149.43403 feet square
Answer is: 866387149.43403 feet square are equivalent to 80.49 kilometers square.
