Chapter 1, Problem 98c
Perform each unit conversion. c. 1845 kg to lb
Verified step by step guidance1
Identify the conversion factor between kilograms and pounds. The conversion factor is 1 kg = 2.20462 lb.
Set up the conversion equation using the conversion factor. Multiply the given mass in kilograms by the conversion factor to convert it to pounds.
Write the equation: \( 1845 \text{ kg} \times \frac{2.20462 \text{ lb}}{1 \text{ kg}} \).
Cancel out the units of kilograms, leaving the units of pounds.
Perform the multiplication to find the mass in pounds.
