Ounces and Grams Explained

Ounces (oz)

An ounce (oz) is the fine-weight unit of the imperial and US customary systems, defined as exactly 28.349523125 g — roughly the weight of a slice of sandwich bread or four toonies stacked up. Sixteen ounces make one pound, so the ounce covers the space where pounds are too coarse: slices at the deli counter, espresso doses, snack packs, and letters all live between a fraction of an ounce and about 16 oz.

Where it is used: Ounces dominate kitchen recipes and packaged goods in the United States, and they still appear alongside grams on bilingual Canadian labels, butcher-shop signage, and restaurant menus.

Origin: The ounce descends from the Roman uncia, one twelfth of a libra. The avoirdupois ounce was fixed internationally in 1959 at exactly 28.349523125 grams — an agreement that keeps Canadian and American scales in sync.

Grams (g)

A gram (g) is the base building block of metric mass, equal to one thousandth of a kilogram. It sits on the scale of everyday precision: a paperclip weighs about 1 g, a toonie 6.9 g, and a standard chocolate bar 45 g. Nutrition Facts tables, pharmacy balances, and spice measures quote grams directly, and because the metric system moves in tens, converting grams to kilograms or milligrams is just a decimal shift.

Where it is used: Grams are the official unit for kitchen scales, Nutrition Facts tables, laboratory work, and retail packaging across Canada — from St. John's to Victoria — and in nearly every other metric country.

Origin: The gram was defined in 1795 as the mass of one cubic centimetre of melting ice water, one of the two founding units of the metric system alongside the metre.

When You Need Ounces to Grams Conversions

Ordering at the Deli Counter

Deli counters from Toronto's Kensington Market to Montreal's smoked meat institutions slice by the pound and ounce, while packaged goods list grams. Knowing 4 oz of roast beef is 113.398 g lets you compare the counter price with supermarket options without guesswork.

Baking American Recipes on a Metric Scale

Recipes from US blogs and cookbooks call for chocolate and nuts in ounces. Converting 6 oz of chopped chocolate to 170.097 g keeps cocoa-to-flour ratios exact — the difference between a showstopper and a doorstop at the bake sale.

Comparing Labels from Cross-Border Shopping

US packaging picked up on cross-border runs lists serving sizes in ounces while Canadian Nutrition Facts tables use grams. A 1 oz serving of trail mix is 28.35 g, so converting lets you compare sodium per gram across brands on either side of the border.

Blending Loose-Leaf Tea

Canadian tea shops often sell loose leaf by the ounce while brewing guides are written in grams. A 2 oz pouch of earl grey converts to 56.699 g, keeping your pot-to-pot flavour consistent.

Frequently Asked Questions

How many grams are in 1 ounce?
1 ounce equals 28.3495 grams (approximately 28.35 g). This is the international avoirdupois ounce used for food and everyday weighing in Canada and the US alike — not the troy ounce of precious metals.
How do I convert ounces to grams for cooking?
Multiply the ounces by 28.3495. Common recipe anchors: 4 oz = 113.398 g, 8 oz = 226.796 g, 12 oz = 340.194 g, and 16 oz = 453.592 g (exactly one pound). Handy whenever a recipe from a US food blog meets your metric scale.
Is a fluid ounce the same as a regular ounce?
No. A fluid ounce measures volume, while this converter handles weight (avoirdupois ounces). They only nearly coincide for water: 1 US fl oz of water weighs about 29.57 g, slightly more than the 28.35 g weight ounce. And the countries even disagree on fluid ounces — the older imperial fluid ounce still seen on some Canadian labels is only 28.41 mL.
Does this converter work for gold and silver?
No — precious metals are traded in troy ounces, about 31.1 g each. Canadian Gold and Silver Maple Leaf coins are sold in troy ounces, while this tool uses the avoirdupois ounce (28.3495 g) found on food labels and at the deli counter.
What is 3 oz of meat in grams?
3 ounces of meat equals 85.05 g — the classic deck-of-cards portion, a little over the 75 g cooked-meat serving in Canada's Food Guide.
How many grams is 12 oz?
12 ounces equals 340.194 g (12 × 28.3495 = 340.194) — the classic 12 oz ribeye on a Canadian steakhouse menu or a family-size box of cereal.
Is 30 g about 1 ounce?
Close but not exact. 30 g converts to 1.058 oz, and a true ounce is 28.3495 g — about 1.65 g less. For savoury cooking the difference is trivial; in pastry work, measure the exact 28.35 g.
How many grams is a half ounce?
A half ounce is 14.175 g (0.5 × 28.3495). Envelopes of yeast, packets of spices, and deli cheese slices often come close to 0.5 oz portions, which read as roughly 14 g on metric scales.

Canada went metric decades ago, but ounces never left: steak menus, bulk-store scoops, and cross-border shopping keep them in daily use. The ounce belongs to the imperial and US customary family, where 16 ounces make a pound, while the gram anchors the metric system on every Nutrition Facts table. Our converter applies the exact international avoirdupois standard of 1 oz = 28.3495 g.

Expert Tips for oz to g Conversion

1

Memorize four anchors and interpolate the rest: 1 oz = 28.35 g, 4 oz = 113.4 g, 8 oz = 226.8 g, and 16 oz = 453.592 g. Most recipe amounts fall between them.

2

Butter blocks differ by market: Canadian butter comes in 454 g one-pound blocks, a US stick is 4 oz (113.398 g) — so four American sticks equal exactly one Canadian block — and European blocks run 250 g (8.82 oz). Converting before substituting prevents greasy or dry bakes.

3

Restaurant steak and salmon portions track ounces — 6 oz = 170.1 g, 8 oz = 226.8 g, 12 oz = 340.2 g. That 10 oz New York strip at a Toronto or Calgary steakhouse is about 283.5 g on your scale.

4

Canadian birth announcements still use pounds and ounces even though the clinic chart is metric. The ounce component converts directly — the 8 oz in a 7 lb 8 oz baby is 226.796 g, putting the whole weight at about 3.402 kg.

5

Canada Post sets its rates in gram brackets (up to 30 g, then 50 g), while US postage climbs by the ounce. A letter weighing 1.5 oz is 42.5 g — enough to bump it into the next Canadian bracket, so weigh on a gram scale before sealing the envelope.
