To help compare different orders of magnitude this page lists areas between 0.1 and 1.0 m². See also areas of other orders of magnitude. Areas smaller than 0.1 m² 0.1 m² is equal to: 1 E-1 m² 1.08 square feet. 1000 cm² Area of a square with side length 316 mm. Surface area of a cube with edge length 129 mm. Area of a circle with radius 178 mm. Surface area of a sphere with radius 89 mm. 0.125 m² -- size of a European A3 paper sheet 297 x 420 mm. Approximate front size of a tabloid (evening) newspaper. 0.250 m² -- size of a European A2 paper sheet 420 x 594 mm. Approximate front size of a (morning) newspaper. 0.45 m² -- a spread broadsheet newspaper 0.500 m² -- size of a European A1 paper sheet 594 x 840 mm Areas larger than 1.0 m² Orders of magnitude for area 1 E−30 m2 = 1 fm2 1 E−24 m2 = 1 pm2 1 E−18 m2 = 1 nm2 1 E−12 m2 = 1 µm2 1 E−6 m2 = 1 mm2 1 E0 m2 = 1 m2 1 E+6 m2 = 1 km2 1 E+12 m2 = 1 Mm2 1 E+18-24 m2 : 1 Gm2 10 fm2 10 pm2 10 nm2 10 µm2 10 mm2 10 m2 10 km2 10 Mm2 > 1 E+24 m2 : 1 Tm2 100 fm2 100 pm2 100 nm2 100 µm2 100 mm2 = 1 cm2 100 m2 = 1 a 100 km2 100 Mm2   1,000 fm2 1,000 pm2 1,000 nm2 1,000 µm2 10 cm2 10 a 1,000 km2 1,000 Mm2   10,000 fm2 10,000 pm2 10,000 nm2 10,000 µm2 100 cm2 10,000 m2 = 1 ha 10,000 km2 10,000 Mm2   100,000 fm2 100,000 pm2 100,000 nm2 100,000 µm2 1,000 cm2 10 ha 100,000 km2 100,000 Mm2   SI derived unit square metre, from base unit metre Conversion of units for area This box: view · talk ·
