Solution 45E: Unit conversion (a) millimeter(mm) to nanometer(nm) We know (i) Convert mm to m -3 1.0 mm = 10 m (ii) nm to m 1 nm = 10 m-9 Thus Given unit x Desired un= desired unit 1 x 103 mn u1 nm 6 1 mm x 1 mm x 109 m = 10 nm 6 Thus, 1.0 mm = 1 x 10 nm (b) mg to kg, We know 10 mg = 1 g and 1 mg = 10 g -3 10 g = 1 kg Therefore 1 x103 g 1 kg 1.0 mg x 1.0 mg x 1000g = 1x 10 kg Therefore, 1 mg is equal to 1x 10 kg -6 (c) km to...
