Answer
1 $hm^{2}$ = 2.47 acres
Work Step by Step
1 hm = 10000 cm
1 in = 2.54 cm
2.54 cm = 1 in
1 cm = 1 / 2.54 in
1 cm = 0.3937007874 in
10000 cm = 3937.007874 in
So 1 hm = 3937.007874 in
1 ft = 12 in
12 in = 1 ft
1 in = 1 / 12 ft
1 in = 0.08333333 ft
3937.007874 in = 3937.007874 * 0.08333333 ft = 328.0839894 ft
So 1 hm = 328.0839894 ft
1 mi = 5280 ft
5280 ft = 1 mi
1 ft = 1 / 5280 mi
1 ft = 0.0001893939394 mi
328.0839894 ft = 328.0839894 * 0.0001893939394 mi = 0.0621371192 mi
So 1 hm = 0.0621371192 mi
1 $hm^{2}$ = 0.0621371192 mi * 0.0621371192 mi
1 $hm^{2}$ = 0.0038610216 $mi^{2}$
1 $mi^{2}$ = 640 acres
0.0038610216 $mi^{2}$ = 0.0038610216 * 640 acres = 2.471053824 acres
So 1 $hm^{2}$ = 2.471053824 acres
Rounding to 3 significant figures gives 2.47 acres.
