Weight Conversion Charts: Kilograms to Pounds, Ounces to Grams
Published November 3, 2026 · By Ahmad Parvez
Weight conversions come up in three places: body weight and gym plates (kilograms against pounds), the kitchen (ounces against grams), and parcels (everything against everything). This page charts all three, with the formulas so you can check any figure the charts skip.
Kilograms to pounds chart
| kg | lbs | kg | lbs |
|---|---|---|---|
| 1 | 2.20 | 15 | 33.07 |
| 2 | 4.41 | 20 | 44.09 |
| 3 | 6.61 | 25 | 55.12 |
| 4 | 8.82 | 30 | 66.14 |
| 5 | 11.02 | 40 | 88.18 |
| 6 | 13.23 | 50 | 110.23 |
| 7 | 15.43 | 60 | 132.28 |
| 8 | 17.64 | 70 | 154.32 |
| 9 | 19.84 | 80 | 176.37 |
| 10 | 22.05 | 90 | 198.42 |
| 100 | 220.46 |
Formulas: pounds = kg × 2.2046. Kilograms = lbs ÷ 2.2046. For a fast mental estimate, double the kilograms and add a tenth: 70 kg → 140 + 14 = 154 lbs — within half a pound of exact.
Ounces to grams (the kitchen chart)
| oz | grams | oz | grams |
|---|---|---|---|
| 0.25 | 7.1 | 5 | 141.7 |
| 0.5 | 14.2 | 6 | 170.1 |
| 1 | 28.35 | 8 | 226.8 |
| 2 | 56.7 | 10 | 283.5 |
| 3 | 85.0 | 12 | 340.2 |
| 4 | 113.4 | 16 (1 lb) | 453.6 |
Formulas: grams = oz × 28.3495. Ounces = grams ÷ 28.3495. Baking is where this chart earns its place: a recipe calling for 8 oz of flour wants 227 g on a metric scale, not a cup guess — and butter helpfully converts at roughly 113 g per US stick (4 oz).
Grams to ounces chart
| grams | oz | grams | oz |
|---|---|---|---|
| 50 | 1.76 | 400 | 14.11 |
| 100 | 3.53 | 500 | 17.64 |
| 150 | 5.29 | 750 | 26.46 |
| 200 | 7.05 | 1,000 (1 kg) | 35.27 |
| 250 | 8.82 | ||
| 300 | 10.58 |
Stone, pounds and kilograms
British body weight mixes the systems: 1 stone = 14 pounds = 6.3503 kg. To convert stone to kilograms, multiply by 6.3503 (10 stone = 63.5 kg). Stone-and-pounds to kg: convert the pounds part too — 11 stone 7 lbs is 161 lbs total, × 0.4536 = 73.0 kg. In the other direction, kilograms to stone: divide kg by 6.3503 (80 kg ≈ 12.6 stone, spoken as 12 stone 8).
Worked examples
- Luggage: a 23 kg airline allowance in pounds — 23 × 2.2046 = 50.7 lbs.
- A parcel: 3 lbs 8 oz — that is 3.5 lbs, × 0.4536 = 1.59 kg.
- Flour: a 1 kg bag in ounces — 1,000 ÷ 28.3495 = 35.27 oz.
- Gym plates: a 20 kg plate is 44.09 lbs; a full 20 kg barbell plus two 20 kg plates totals 60 kg = 132.3 lbs.
Every figure above can be checked — and any unlisted weight converted — in the weight converter, which also handles tons and milligrams.
Frequently asked questions
How many pounds is 70 kg?
70 kg is 154.32 pounds. Multiply kilograms by 2.2046: 70 × 2.2046 = 154.32 lbs. For a quick estimate, double the kg and add a tenth (140 + 14 = 154).
How many grams are in an ounce?
There are 28.3495 grams in one avoirdupois ounce — the ounce used for food and parcels. In practice 28.35 g is used everywhere; a troy ounce (precious metals) is different at 31.1035 g.
How do I convert pounds to kilograms?
Divide the pounds by 2.2046, or multiply by 0.4536. For example, 150 lbs × 0.4536 = 68.04 kg, and 200 lbs = 90.72 kg.
Is 500 grams a pound?
Not quite — 500 grams is 1.1023 pounds, about 10% over a pound. A true pound is 453.59 grams, which is why a '500 g' pack is slightly more generous than a '1 lb' pack.
How much is 10 stone in kg?
10 stone is 63.5 kg. One stone is 14 pounds, and 14 lbs × 0.4536 = 6.3503 kg, so multiply the stone by 6.3503: 10 × 6.3503 = 63.50 kg.
Why do recipes in ounces and grams disagree with cups?
Cups measure volume and ounces/grams measure weight — a cup of flour (≈120 g) and a cup of sugar (≈200 g) differ wildly. Converting the recipe's ounces to grams with this chart and weighing ingredients is the reliable route, especially for baking.
