Here are the conversions of the given masses into kilograms: a) Convert 58\,475\, to kilograms. Step 1: Convert micrograms to grams. 58\,475\, × 1\, g1\,000\,000\, = 0.058475\, g Step 2: Convert grams to kilograms. 0.058475\, g × 1\, kg1\,000\, g = 0.000058475\, kg The mass is 0.000058475 kg. b) Convert 406\, dg to kilograms. Step 1: Convert decigrams to grams. 406\, dg × 1\, g10\, dg = 40.6\, g Step 2: Convert grams to kilograms. 40.6\, g × 1\, kg1\,000\, g = 0.0406\, kg The mass is 0.0406 kg. c) Convert 1\,900\, cg to kilograms. Step 1: Convert centigrams to grams. 1\,900\, cg × 1\, g100\, cg = 19\, g Step 2: Convert grams to kilograms. 19\, g × 1\, kg1\,000\, g = 0.019\, kg The mass is 0.019 kg. d) Convert 65\, Mg to kilograms. Step 1: Convert megagrams to kilograms. (Note: 1\, Mg = 1\,000\, kg) 65\, Mg × 1\,000\, kg1\, Mg = 65\,000\, kg The mass is 65000 kg. e) Convert 945\, Dg to kilograms. Step 1: Convert decagrams to grams. 945\, Dg × 10\, g1\, Dg = 9\,450\, g Step 2: Convert grams to kilograms. 9\,450\, g × 1\, kg1\,000\, g = 9.45\, kg The mass is 9.45 kg. f) Convert 1\,854\, mg to kilograms. Step 1: Convert milligrams to grams. 1\,854\, mg × 1\, g1\,000\, mg = 1.854\, g Step 2: Convert grams to kilograms. 1.854\, g × 1\, kg1\,000\, g = 0.001854\, kg The mass is 0.001854 kg. g) Convert 23\, tonnes to kilograms. Step 1: Convert tonnes to kilograms. (Note: 1\, tonne = 1\,000\, kg) 23\, tonnes × 1\,000\, kg1\, tonne = 23\,000\, kg The mass is 23000 kg. h) Convert 125\, Hg to kilograms. Step 1: Convert hectograms to grams. 125\, Hg × 100\, g1\, Hg = 12\,500\, g Step 2: Convert grams to kilograms. 12\,500\, g × 1\, kg1\,000\, g = 12.5\, kg The mass is 12.5 kg. i) Convert 40\,500\, g to kilograms. Step 1: Convert grams to kilograms. 40\,500\, g × 1\, kg1\,000\, g = 40.5\, kg The mass is 40.5 kg. That's 2 down. 3 left today — send the next one.
