1. How many kilograms are in 44.8 tons? 44.8 tons = ? kg
Solve by dimensional analysis. Use
1 ton = 2000 lb
1 lb = 453.59 g

4.06 × 10⁴ kg

Explanation:

Step 1: Given data

Mass (m): 44.8 ton

Step 2: Convert "m" to pounds

We will use the conversion factor 1 ton = 2,000 lb .

44.8 ton × (2,000 lb/1 ton) = 8.96 × 10⁴ lb

Step 3: Convert "m" to grams

We will use the conversion factor 1 lb = 453.59 g.

8.96 × 10⁴ lb × (453.59 g/1 lb) = 4.06 × 10⁷ g

Step 4: Convert "m" to kilograms

We will use the conversion factor 1 kg = 1,000 g.

4.06 × 10⁷ g × (1 kg/1,000 g) = 4.06 × 10⁴ kg
