Pound (lb) = Gram (g) × 0.00220462262185
Gram (g): The gram is one thousandth of a kilogram, the SI base unit of mass. It is used worldwide for food, postage and small quantities of almost anything.
Pound (lb): The avoirdupois pound has been defined since 1959 as exactly 0.45359237 kilograms and is divided into 16 ounces. It is the everyday unit of weight in the US.

| 1 | 0.00220462262185 |
| 5 | 0.0110231131092 |
| 10 | 0.0220462262185 |

Hospitals in most countries, drone makers and sports rule books give weights in grams, and many US readers want the figure in pounds, or in pounds and ounces. A pound is defined as exactly 453.59237 g, so dividing grams by that number gives pounds, and the first chart also splits each answer into pounds and ounces.
Birth weight is the most common example: a baby weighed at 3,500 g goes on a US-style chart as 7 lb 11.5 oz. The same split works for parcels and packaged food, where a 500 g pack comes to just over a pound. Drones are another case: in the US, registration starts above 250 g, a little over half a pound.

Quick mental estimate
Treat the grams as kilograms and multiply by 2.2: 2,500 g → 2.5 × 2.2 = 5.5 lb. The 2.2 factor is about 0.2% below the exact 2.20462, so the shortcut comes out a little light; dividing the grams by 453.6 gives a closer figure.
Use the converter or the charts when the exact figure matters.
