The kilogram and the pound are units measuring mass. The kilogram is in the metric system, governed by the International System of Units (SI). The pound, on the other hand, is in the United States customary or "imperial" system. In everyday, modern usage terms, these units measure weight. For example, human and animal body weights are either in kilograms or pounds, depending on the country or region. Conversion from kilograms to pounds or vice versa involves a simple multiplication equation. The equation is workable with paper, pencil and calculator.
Use the pencil to write the word "Legend" at the top of the paper.
Move down one line below the word "Legend" and write the following: "Kilograms to pounds: 1 kilogram (kg) = 2.20462262185 pounds (lbs.)"
Move down another line and write the following: "Pounds to kilograms: 1 pound (lb.) = 0.45359237 kilograms (kg)."
Move down one more line and write the following: "Multiplication equation: Multiplicand x Multiplier = Product."
Draw a line under and/or around this section.
Move down below the entire Legend, and write your kilogram measurement on the paper; this is the "multiplicand," or first number in a multiplication equation. For example, write "100 kg." Write the sign for multiplication, either an "X" or "asterisk."
Look up at the Legend and refer the "Kilograms to pounds" conversion. Write the "pounds" value, "2.20462262185," after the sign; this is the "multiplier." Add an "equal sign."
Turn on the calculator. Type the multiplicand into the calculator. Press the sign for multiplication ("X" or "asterisk"). Type the multiplier. Press the "equal" sign.
Write the final solution from your calculator screen as the "product" of your multiplication equation and add the pounds unit.
Move down one line below your final calculation from the previous step and write the product: "100kg." Write the multiplication sign after that.
Use your calculator again, to multiply the product, which is in pounds, by the "pounds to kilograms" conversion to verify your calculations are correct: "100000012566kg. x 0.45359237 = 100 kg." Write this on your paper.
If you arrive back at your original kilogram measurement, then your conversion was correct.
Check your writings against this example:
Kilograms to pounds: 1 kilogram (kg) = 2.20462 (lbs.) Pounds to kilograms: 1 pound (lb.) = 0.45359237 kilograms (kg) Multiplication equation: Multiplicand x Multiplier = Product
(Line of separation)
100kg x 2.20462262185 = 100000012566kg.
100000012566kg. x 0.45359237 = 100 kg."
Seek out an online kilograms to pounds conversion calculator, such as the one offered by Google.
Be careful with decimals in your initial calculations. Try to include all numbers, and then only round down to two or three decimal points after you solve the equation.
