A3 is approx 193.75 in2
The A series of paper is designed so that A(n+1) is half the area of An and A0 is 1m2.
⇒ A3 is half A2 is half A1 is half A0
⇒ A3 is 1/8m2 = 0.125m2
1m = 100cm
1m2 = 1m x 1m
= 100cm x 100cm
= 10000cm2
1in =2.54cm (exactly)
1in2 = 1in x 1in
= 2.54cm x 2.54cm
= 6.4516cm2
⇒ A3 = 0.125m2
= 1250cm2
= 1250 ÷ 6.4516 in2
~= 193.75 in2
