How to convert 5.5 kilograms to pounds and ounces step-by-step

One kilogram is a unit of mass (not weight) which equals to approximately 2.2 pounds. One pound equals 16 ounces exactly. If you need to be super precise, you can use one kilogram as 2.2046226218488 pounds. Once this is very close to 2.2 pounds, you will almost always want to use the simpler number to make the math easier.

Step 1: Convert from kilograms to pounds

1 kilogram = 2.2 × pounds, so,

5.5 × 1 kilogram = 5.5 × 2.2 pounds (rounded), or

5.5 kilograms = 12.1 pounds.

Step 2: Convert the decimal part in pounds to ounces

An answer like "12.1 pounds" might not mean much to you because you may want to express the decimal part, which is in pounds, in ounces which is a smaller unit.

So, take everything after the decimal point (0.1), then multiply that by 16 to turn it into ounces. This works because one pound equals 16 ounces. Thus,

12.1 pounds = 12 + 0.1 pounds = 12 pounds + 0.1 × 16 ounce = 12 pounds + 1.6 ounces. So, 12.1 pounds = 12 pounds and 1 ounce (when rounded). Obviously, this is equivalent to 5.5 kilograms.

Step 3: Convert from decimal ounces to a usable fraction of ounce

The previous step gave you the answer in decimal ounces (1.6), but how to express it as a fraction? See below a procedure, which can also be made using a calculator, to convert the decimal ounces to the nearest usable fraction:

a) Subtract 1, the number of whole ounces, from 1.6:

1.6 - 1 = 0.6. This is the fractional part of the value in ounces.

b) Multiply 0.6 times 16 (it could be 2, 4, 8, 16, 32, 64, ... depending on the exactness you want) to get the number of 16th's ounces:

0.6 × 16 = 9.6.

c) Take the integer part int(9.6) = 10. This is the number of 16th's of a pound and also the numerator of the fraction.

Finalmente, 5.5 quilogramas = 12 pounds 1 9/16 ounce.

In short:

5.5 kg = 12 pounds 1 9/16 ounce

Important! This result may differ from the calculator above because we've assumed here that 1 kilogram equals 2.2 pounds instead of 2.2046226218488 pounds.
