Inch Square (abbreviations: in2, or si): (plural: square inches) is a unit of area, equal to the area of a square with sides of one inch.
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.
How to Convert Inches Square to Kilometers Square
Example: How many kilometers square are equivalent to 19.42 inches square?
As;
1 inches square = 6.4516E-10 kilometers square
19.42 inches square = Y kilometers square
Assuming Y is the answer, and by criss-cross principle;
Y equals 19.42 times 6.4516E-10 over 1
(i.e.) Y = 19.42 * 6.4516E-10 / 1 = 1.25290072E-8 kilometers square
Answer is: 1.25290072E-8 kilometers square are equivalent to 19.42 inches square.
