Question

A Nimitz-class aircraft carrier weighs 98000 tons. If 1 ton is 2000 lbs and 1 kg is 2.2 lbs, how many gigagrams does a Nimitz-class aircraft carrier weigh?

1 gigagram = 1 billion grams

Answer 1

9.8 x 10⁴ tons

1.96 x 10⁸ lbs        multiply by 2000

4.312 x 10⁸ kg       multiply by 2.2

4.312 x 10¹¹ gm    multiply by 1000

4.312 x 10²           divide by 10⁹
