Weight Converter: Grams, Ounces, Pounds, kg, Stone

A recipe can give weight in grams, ounces, pounds, or kilograms depending on where it was written, and older recipes reach for stranger units still. Enter the amount, pick your units, and read the equivalent instantly. The common values table below shows everyday gram amounts in ounces, pounds, and kilograms at a glance. Useful when:

  • Converting grams to ounces: enter the grams and read the ounce figure for any American recipe.
  • Converting kg to lb: swap kilograms for pounds when a bulk ingredient is sold one way and your recipe wants the other.
  • Weighing in stone: the 14-pound stone is included for large quantities and old British recipes.
  • Measuring tiny amounts: milligrams, carats, and grains cover the small end of the scale.
  • Following a historic recipe: the shekel, mina, dram, and talent are all supported.

Grams, Ounces, and Pounds

Most modern weight conversions move between two systems. The metric system anchors everything to the gram and kilogram and is used for cooking throughout Europe, Australia, and most of the world. The imperial and US customary systems keep the ounce and the pound, where one ounce is 28.35 grams and one pound is 16 ounces, or 453.59 grams. A kilogram is about 2.205 pounds, which is why a 1 kg bag of flour reads as a little over 2 lb on an American scale. The converter above labels each unit clearly so you always know which system you are working in. For the difference between weighing and measuring by volume, the grams to cups converter handles ingredient-specific volume.

Historic Weight Units

Before standardised scales, weights were stacked up from seeds and grains. The grain, the weight of a single dried barley grain at about 0.065 g, was the base. Twenty grains made a scruple and three scruples a dram, both of which survive in the apothecary system. The Hebrew shekel was roughly 11.4 g, fifty shekels made a mina, and sixty minas a talent, a load near 34 kg. These all appear in the unit list above. For the full story behind each one, see the ancient and obscure measurements guide.

Frequently Asked Questions

How do you convert grams to ounces?
Divide the number of grams by 28.35, since one ounce is 28.349523125 grams. So 100 grams is about 3.527 ounces and 250 grams is about 8.82 ounces. Weight conversion is ingredient-independent, so the same gram figure gives the same ounce figure whether you are weighing flour, sugar, or butter. The converter above handles any amount instantly.
How do you convert kg to lb?
Multiply kilograms by 2.205 to get pounds, since one kilogram is about 2.2046 pounds. So 1 kg is roughly 2.205 lb and 5 kg is about 11.02 lb. To go the other way, divide pounds by 2.205. The converter above does both directions for any value, and you can switch to ounces or grams from the same dropdown.
How many grams are in an ounce?
One ounce is 28.349523125 grams, usually rounded to 28.35 g in the kitchen. A pound holds 16 ounces, which works out to 453.59 grams. Most recipes round an ounce to 28 g, and the small difference rarely matters for a single ingredient, though it can add up across a large bake where precise ratios count.
What is a stone in kg and lb?
A stone is 14 pounds, which is about 6.35 kilograms. It is a British and Irish unit still used for body weight rather than cooking, but it appears in old recipes and bulk-ingredient orders. To convert, multiply stones by 14 for pounds or by 6.35 for kilograms. The converter above includes the stone alongside grams, ounces, and pounds.
How many grams is one carat?
One metric carat is exactly 0.2 grams, or 200 milligrams. It is used for gemstones and pearls rather than food, but it is a handy reference for very small weights and turns up in lists of obscure units. Five carats make one gram. Select carat in the converter above to translate it into grams, milligrams, or grains.
What are ancient weight units like the shekel?
Old weights were built up from seeds. A grain is about 0.065 g, 20 grains make a scruple, and three scruples make a dram. The Hebrew shekel was roughly 11.4 g, 50 shekels made a mina (571 g), and 60 minas made a talent (about 34 kg). The converter above includes all of these, and the guide explains where each came from.
