Answer 1

1] 1Kg = 1000 gms

1gm = 1000 mg

1Kg = 10^6 mg

1.5 Kg = 1.5*10^6 mg

2] 1 ft =30.48 cm

6ft = 6*30.48 = 183 cm

3] 1 gallon = 3.79 L

3.87 gallons = 3.87*3.79 = 14.6673 L

4] 1 in = 2.54 cm

4.57 in = 11.607 cm

11.607 cm = 11.607*10^-2 metres

11.607*10^-2 *10^-9 / 10^-9 = 11.607*10^7 nm = 116070000
