How do you convert pounds to kilograms and what is atto?

To convert mass in pounds to kilograms approximately, multiply the number of pounds by zero point four five four to get kilograms, for example one hundred twenty pounds is about fifty five kilograms, and the metric prefix atto means one quintillionth or ten to the power of negative eighteen of a unit.

Think of pounds and kilograms as different names for how heavy something is, like having two different measuring cups for the same amount of water; to change from pounds to kilograms you use a fixed conversion number, zero point four five four, and you multiply the pounds by that number so the weight becomes kilograms, so if you have twenty pounds you multiply twenty by zero point four five four to get about nine point zero eight kilograms, and the prefix atto is very tiny and is used when scientists measure unbelievably small things, so one attojoule is one quintillionth of a joule and you might see it when measuring single atoms or tiny particles.

A common mistake is forgetting to use the full conversion number and instead using zero point four five, which makes the answer slightly small, so always use zero point four five four or write the exact fraction two hundred and two point eight three four divided by four hundred and forty nine if you want more precision; another error is mixing up the direction and multiplying kilograms by zero point four five four when you actually need to divide by zero point four five four to go from kilograms to pounds, so check which way you are converting before you calculate; students also sometimes think atto means a large number because it sounds like “atomic” or “attack,” so remember atto is a very small fraction and spell it out as one quintillionth to keep it clear.
