Convert Pounds to Grams: The Short Answer
1 pound = 453.592 grams. For kitchen work, use 454 g. Half a pound is 227 g, a quarter pound is 113 g, and a kilogram is 2.205 pounds — which is why a 1 kg bag of flour is labelled 2 lb 3 oz in the US.
The reason so many recipes live in both units is that American groceries are sold in pounds while professional formulas, nutrition labels, and most of the world work in grams. This page is the bridge: one multiplier, one chart, and the three rounding decisions that actually matter.
The Formula, Both Directions
Two lines are all you need. Memorise the first and derive the second.
grams = pounds × 453.592 pounds = grams ÷ 453.592
At kitchen scale, the shortcut is accurate enough: × 454 going to grams, ÷ 454 coming back. The error is 0.09% — under half a gram per pound — which is below the tolerance of any home recipe.
A quicker mental version for small amounts: 1 lb ≈ 450 g, 1 kg ≈ 2.2 lb. That is the pair of numbers to keep in your head for grocery-store arithmetic, where being 1% off costs you nothing.
Pounds to Grams Chart
| Pounds | Grams | Pounds | Grams |
|---|---|---|---|
| ¼ lb | 113 g | 5 lb | 2,268 g |
| ⅓ lb | 151 g | 6 lb | 2,722 g |
| ½ lb | 227 g | 7 lb | 3,175 g |
| ⅔ lb | 302 g | 8 lb | 3,629 g |
| ¾ lb | 340 g | 10 lb | 4,536 g |
| 1 lb | 454 g | 12 lb | 5,443 g |
| 1.5 lb | 680 g | 15 lb | 6,804 g |
| 2 lb | 907 g | 20 lb | 9,072 g |
| 2.2 lb | 998 g | 22 lb (10 kg) | 9,979 g |
| 3 lb | 1,361 g | 25 lb | 11,340 g |
| 4 lb | 1,814 g | 30 lb | 13,608 g |
Two lines in that table are worth flagging. 2.2 lb = 998 g, so a recipe calling for 2.2 lb of anything is asking for a kilogram; buy the 1 kg bag and stop converting. And 4 lb = 1.814 kg, which is the unit professional bakeries call a “5-pound bag after you account for the fact that a 5 lb bag is 2.27 kg.” Labels and reality disagree more often than you would expect.
Pounds Plus Ounces: The Grocery Case
American recipes and packages love mixed units — “1 lb 4 oz of chuck,” “2 lb 6 oz chicken.” Rather than doing two conversions and adding, compute the whole thing in ounces first, then convert once:
grams = (pounds × 16 + ounces) × 28.3495
| Weight | Working | Grams |
|---|---|---|
| 1 lb 4 oz | 20 oz × 28.35 | 567 g |
| 1 lb 8 oz | 24 oz × 28.35 | 680 g |
| 2 lb 6 oz | 38 oz × 28.35 | 1,077 g |
| 3 lb 5 oz | 53 oz × 28.35 | 1,502 g |
| 5 lb 8 oz | 88 oz × 28.35 | 2,495 g |
This is the calculation that matters when a butcher counter weighs your pork shoulder and prints “4 lb 11 oz” on the ticket, and the recipe you found online says “2.1 kg.” Multiply the ounces by 28.35 and you have your answer: 2,126 g.
What a Pound Looks Like in Every Common Kitchen Item
Pounds mean different things depending on what is on the label, and knowing the equivalences saves a trip to the scale.
| Item | 1 lb equals |
|---|---|
| Butter | 4 sticks (454 g) |
| All-purpose flour | ~3⅔ cups (454 g) |
| Granulated sugar | ~2¼ cups (454 g) |
| Brown sugar, packed | ~2⅔ cups (454 g) |
| Powdered sugar | ~3¾ cups (454 g) |
| Rolled oats | ~5 cups (454 g) |
| Chocolate chips | ~2¾ cups (454 g) |
| Coffee beans | ~4½ cups (454 g) |
| Dry pasta | 4–5 servings (454 g) |
| Honey | ~1⅓ cups (454 g) |
Read the butter line carefully, because it is the one place where US and metric recipes collide most often. A pound of butter is four sticks of 113 g each, and a European recipe asking for 250 g is asking for two sticks plus a sliver — 227 g plus 23 g. Get this wrong in a laminated dough and the layers will tell on you.
When the Difference Between 454 g and 450 g Matters
For most cooking, rounding a pound to 450 g is harmless. There are three situations where it is not:
Bread and baker’s percentages. A formula written as “100% flour, 70% water” only works if every ingredient is measured on the same scale. If you round 2 lb of flour to 900 g instead of 907 g, your hydration drifts by about 0.5% — not fatal, but if you round the flour down and the water up, the errors compound. Weigh flour in grams and never convert mid-formula. The Dough Hydration Calculator takes the flour weight as its base and computes everything else as a percentage of it, which removes the ambiguity entirely.
Curing and brining. Salt ratios are calculated against meat weight. A 5 lb brisket is 2,268 g, not 2,250 g; at a 2% equilibrium cure the difference is 0.4 g of salt, which is genuinely negligible — but the same logic applied to a 20 lb turkey is 9,072 g versus 9,000 g, and that 72 g gap moves your salt dose by 1.4 g. Small, but you are measuring salt to the gram anyway, so use the real number. The Brine Calculator works in both units and does the percentage maths for you.
Fine pastry and confectionery. Ganache, caramel, and tempering all depend on exact ratios of fat to sugar to water. A 7 g swing in a 454 g batch is 1.5%, which is the margin between a glossy temper and a streaky one.
Everywhere else — a stew, a roast, a tray of brownies — round to 450 g and get on with it.
Rounding Rules Worth Following
- Under 1 lb: round to the nearest gram. ¼ lb = 113 g, not 110 g.
- 1–5 lb: round to the nearest 5 g. 2 lb = 905 g is fine.
- Over 5 lb: work in kilograms and keep two decimals. 10 lb = 4.54 kg.
- Never round twice. Convert once from the original unit, not from an already-rounded figure.
- Round the salt last. Seasoning is the one ingredient where a 2 g error is detectable; everything else tolerates more than you think.
Converting a Whole Recipe Between Systems
If one recipe is in pounds and another is in grams, the safest move is to convert the entire thing once and rewrite it, rather than converting measurements on the fly mid-cook. The Kitchen Measurement Converter handles pounds, ounces, grams, cups, and millilitres together for sixteen common ingredients, so a full grocery list can be translated in one pass. If the batch size changes while you are at it, the Recipe Servings Calculator rescales every line at once.
