Convert 5 kg to pounds Step by Step

Step by step

The question

Question: change 5 kilograms into pounds.

5 kg = ? lb

1 Find the link

1 kilogram is about 2.2 pounds.

This link is rounded, so our answer is rounded too: to the nearest tenth.

1 kg ≈ 2.2 lb

2 Make the unit fraction

We want pounds, so pounds go on top.

We have kilograms, so kilograms go at the bottom.

Top and bottom are the same amount.

So the fraction is 1, and times 1 keeps the size.

2.2 lb1 kg ≈ 1

Careful!

Not upside down.

Then the kilograms would not cross out.

Careful: not 5 kg × 1 kg2.2 lb ✗

3 Multiply

We multiply 5 kilograms by the fraction.

5 kg = 5 kg × 2.2 lb1 kg

Kilograms on top and at the bottom cancel, like numbers.

Cross them out.

Pounds are left.

What is left: 5 times 2.2.

= 5 × 2.2 lb

5 times 2.2 is 11.

So 5 kilograms is about 11 pounds.

≈ 11 lb

4 Check

Does it make sense?

Pounds are smaller than kilograms.

So we need more of them.

11 is more than 5.

Yes.

lb smaller than kg → more: 11 > 5

And back the other way: 11 divided by 2.2 = 5.

We get 5 kilograms again.

So the answer is right!

back: 11 ÷ 2.2 = 5

Let's look back.

First: find the link.

Then: make the unit fraction.

Then: multiply.

Last: check.
