Answer 1

What are units?

A unit can be used for measurement, and is commonly found in mathematics to describe length, size, etc.

First, we need to know the conversion rate between the two units (pounds lb and kilograms kg)

• 1 pound = 0.45359237 kilograms

Now, we can convert 90 pounds.

• 90 × 0.45359237 = 40.8233133 kg

So, 90lb ≈ 41kg

(If you were to round)
