Step by step
500 / 453.59237 = 1.1023
- A pound is exactly 453.59237 g, so divide the grams by 453.59237: 500 / 453.59237 = 1.1023 lb.
- For pounds and ounces, change to ounces first (1 oz = 28.349523125 g): 500 / 28.349523125 = 17.637 oz. Counting 16 oz for each whole pound, that is 1 lb 1.64 oz.
- In kilograms: 500 / 1000 = 0.5 kg.

How it works
The pound used in the United States is defined as exactly 453.59237 grams (0.45359237 kg). To convert grams to pounds, divide by 453.59237, or multiply by about 0.0022046. So 500 g is 1.1023 lb, 100 g is 0.2205 lb and 1,000 g, one kilogram, is 2.2046 lb. To go the other way, multiply the pounds by 453.59237: 1 lb is 453.59 g and 2 lb are 907.18 g.
Many weights read better as pounds and ounces. A pound has 16 ounces and an ounce is exactly 28.349523125 g, so divide the grams by 28.3495 to get ounces, take out 16 ounces for each whole pound and keep the rest. 500 g is 17.64 oz, which is 1 lb 1.64 oz, and 450 g is 15.87 oz, just under a pound. In the other direction enter the pounds and the extra ounces, for example 7 lb 8 oz for a newborn, which is 3,401.94 g.
US food packages round the pound to 454 g, and 8 oz to 227 g and 12 oz to 340 g, so a recipe or label that says 454 g means one pound; the exact value is 453.59 g. A 500 g pack from a metric recipe is about 10% more than a pound. Grams measure weight, so the answer does not depend on the ingredient. For cups and tablespoons see the cups to ounces converter, for ounces and pounds the ounces to pounds converter and for kilograms the kg to lbs converter.
The formula
The pound is defined in kilograms, so the factor is exact and the only rounding is in the digits shown. The reciprocal is 1 / 453.59237 = 0.00220462262185..., so the often quoted 0.0022046 is already rounded. The converter divides by the exact 453.59237, which keeps large weights right to the last shown decimal.
The remaining ounces are shown to two decimals. A weight less than 0.005 oz below a whole pound is carried up to that pound, so 453.5 g shows 1 lb 0 oz instead of 0 lb 16.00 oz; the decimal pounds are not changed by this. When you add extra ounces to pounds, every 16 ounces carry into one more pound, so 0 lb 20 oz is 1.25 lb.
