How to convert 9.89 kilograms to pounds and ounces step-by-step
One kilogram is a unit of masss (not weight) and equals approximately 2.2 pounds. One pound equals 16 ounces exactly. If you need to be super precise, you can use one kilogram = 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 x pounds, so,
9.89 x 1 kilogram = 9.89 x 2.2 pounds (rounded), or
9.89 kilograms = 21.758 pounds.
Step 2: Convert the decimal part of pounds to ounces
An answer like "21.758 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 (0.76), then multiply that by 16 to turn it into ounces. This works because one pound = 16 ounces. Then,
21.76 pounds = 21 + 0.76 pounds = 21 pounds + 0.76 x 16 ounces = 21 pounds + 12.16 ounces. So, 21.76 pounds = 21 pounds and 12 ounces (when rounded). Obviously, this is equivalent to 9.89 kilograms.
Step 3: Convert from decimal ounces to an usable fraction of once
The previous step gave you the answer in decimal ounces (12.16), but how to express it as an usable (practical) 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 12, the number of whole ounces, from 12.16:
12.16 - 12 = 0.16. This is the fractional part of the value in ounces.
b) Multiply 0.16 times 8 (it could be 8, 16, 32, 64, ... depending on the exactness you want) to get the number of 16th's ounces:
0.16 x 16 = 2.56.
c) Take the integer part:
int(2.56) = 3. This is the number of 16th's of a pound and also the numerator of the fraction.
Finally, 9.89 kilograms = 21 pounds 12 1/8 ounces.
9.89 kg = 21 pounds 12 1/8 ounces
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.
