How do you convert 12 kilograms to pounds using 1 kg = 2.2 lb?

##26.4## lbs

Conversions are always in direct proportion. More of one quantity means more of the other.

Set up equivalent fractions and make sure you match the corresponding values correctly.

(For ease of calculation I like to place the unknown at the top of the left hand side, but it can be anywhere.)

##(lbs)/(kg) ” “x/12 = 2.2/1 ” cross multiply”##

##color(white)(xxxxxxx) x = 12 xx2.2##

##color(white)(xxxxxxx) x = 26.4 lbs##

We could also use the method:

1 kg is the same as 2.2 lbs 12 kg is the same as 12 x 2.2lbs.

However conversions are sometimes not given with one of the quantities as “1” and this makes converting tricky.

The cross multiplication method is quick and easy.
