How to Convert Stone to Pounds

Instructor: Artem Cheprasov
In this lesson, we will learn how to convert stone to pounds using a very simple conversion factor. We will also see how we can convert pounds back to stone as well.

Steps to Solve

Background Information

Stones, in this lesson, are not those hard and rough things found outside. Stone is an Imperial unit of measurement. Specifically, a stone is used to measure weight just like a pound is used to measure weight. A pound is a unit found in the Imperial and United States customary systems of measurement.

One quick important note before we begin. It is improper to say 'stones' for the unit of weight in question! The plural form of 'stone' is also 'stone' in this case. This is much like sheep. 1 sheep, 2 sheep, 108 sheep. 1 stone, 2 stone, 108 stone. You get the idea.

Steps

To convert from stone to pounds is really easy!

Step 1

Remember this conversion factor:

1 stone = 14 pounds

Step 2

Let's stay we want to convert 2 stone into pounds. All you have to do is multiply the weight in stone by 14:

(2 stone) x (14 pounds/stone)

Solution

We see that two two stones is the same as 28 pounds.

(2 stone) x (14 pounds/stone) = 28 pounds

Verifying Your Answer and An Application

Verifying Your Answer

How can we check that our answer is correct? Well, if we have our weight in pounds, 28, then we can back convert to ensure we get to our original weight in stone. Recall:

1 stone = 14 pounds

This means 14 pounds = 1 stone. To back convert from 28 pounds to stone we need to divide the amount of pounds we have by 14 like so:

(28 pounds) / (14 pounds/stone) = 2 stone

We're back to where we started. That means we performed the calculation correctly!
