### The Four Squat Workout

No calculator in your gym bag? Use this to easily convert Kg to Lbs.

By Leather

I was in the gym this morning and trying to convert kilograms to pounds. I asked around until someone told me about an ancient powerlifting formula. Okay, the truth is I asked my father how to do a quick conversion. He is retired now but still hits the gym. Since he was a butcher he worked with lbs for years and only recently had to use KG's when the UK switched. He told me a quick and easy way to convert Kgs to Lbs in your head that I thought I would share with you all.

"Why would I want to do that?" you may ask. Well, in my case I was going for a PR on the press and I wanted to check the number in both pounds and kilograms. This may help you in a similar situation such as when you are trying to hit that 800Lb Deadlift but only have KG plates to pile on!

### How To Do IT

1) Double the Kg figure.
2) Take all but the last digit of the result.
3) Add it to the result.

### Examples

10KG

1) Double it: 20
2) Take all but the last digit of the result: 2
3) Add it to the result: 20 + 2 = 22lbs

100kg

1) Double it: 200
2) Take all but the last digit of the result: 20
3) Add it to the result: 200 + 20 = 220lbs

350kg

1) Double it: 700
2) Take all but the last digit of the result: 70
3) Add it to the result: 700 + 70 = 770lbs

### Limitations

I have tested this from 0 to 4000Kg and it works for 10kg upwards.

### How It Works

There are 2.2lbs in a KG so the formula works by providing an easy way to calculate this. First we double the KG figure which gives us the 2 section of the result and then we just need to calculate the remaining 0.2. Removing the final digit from any number is the same as dividing it by 10, giving us 10% or 0.1 of the original value. Because we have already doubled the original figure this actually gives us the 20% or 0.2 that we need so we simply add the two figures and we have the correct result.

Happy converting!
