If you’re coming from the United States, one of the first practical challenges in Italy will be understanding measurements. Forget pounds, ounces, and gallons — here everything runs on grams, liters, and Celsius. It might seem confusing at first, but with this guide you’ll learn to shop, cook, and order at restaurants just like an Italian.
🔢 Weight: Grams, Kilos, and the Mysterious “Etto”
In Italy, weight is measured in grams (g) and kilograms (kg). But there’s one unit you’ll hear everywhere, especially at markets and delis: the etto.
What is an etto? It’s short for ettogrammo, and it equals 100 grams. Italians use it all the time when buying sliced meats, cheese, meat, or produce.
| Italian Measurement | U.S. Equivalent | Notes |
|---|---|---|
| 1 gram (g) | 0.035 oz | Too small for everyday use |
| 1 etto (100 g) | 3.5 oz | The most common unit! |
| ½ kilo (500 g) | 1.1 lb | “Mezzo chilo” is often used |
| 1 kilo (kg) | 2.2 lb | Standard for fruit and vegetables |
| 1 U.S. pound (lb) | 454 g (around 4.5 etti) | Not used in Italy |
“Mi dia due etti di prosciutto crudo, per favore” = Give me 200g (7 oz) of cured ham, please.
“Vorrei un etto e mezzo di mortadella” = I’d like 150g (5.3 oz) of mortadella.
“Tre etti di parmigiano, grazie” = 300g (10.6 oz) of parmesan cheese.
“Mezzo chilo di pomodori” = Half a kilo (1.1 lb) of tomatoes.
🥤 Liquids: Liters and Milliliters (Goodbye, Gallons!)
In Italy, liquids are measured in milliliters (ml) and liters (l). You won’t find gallons, quarts, or pints in an Italian supermarket.
| Italian Measurement | U.S. Equivalent | Common Example |
|---|---|---|
| 100 ml | 3.4 fl oz | Espresso or small shot |
| 250 ml (¼ liter) | 8.5 fl oz (≈ 1 cup) | Glass of wine |
| 500 ml (½ liter) | 16.9 fl oz | Small water bottle |
| 1 liter (l) | 33.8 fl oz (≈ 4.2 cups) | Water, milk, juice |
| 750 ml | 25.4 fl oz | Standard wine bottle |
| 1 U.S. gallon | 3.8 liters | Not sold in Italy! |
“Una bottiglia d’acqua naturale da un litro” = Still water, 33.8 fl oz.
“Un quarto di vino rosso” = ¼ liter (250 ml), about 8.5 fl oz.
“Mezzo litro di birra alla spina” = Draft beer, 16.9 fl oz.
“Un caffè” = About 30 ml of espresso (1 fl oz) — much smaller than an American coffee!
👨🍳 In the Kitchen: Goodbye Cups, Hello Scale!
This is probably the biggest difference: Italian recipes don’t use cups. Everything is measured in grams and milliliters, so you’ll need a digital kitchen scale.
| Italian Measurement | U.S. Equivalent | Used For |
|---|---|---|
| 1 cucchiaino (tsp) | 5 ml | Spices, yeast, salt |
| 1 cucchiaio (tbsp) | 15 ml | Oil, vinegar, sugar |
| 1 bicchiere d’acqua | ≈ 200 ml (not precise!) | Homemade “glass” measure |
| Digital scale | Essential! | For flour, sugar, butter, etc. |
1 cup of flour = about 120–130g
1 cup of sugar = about 200g
1 cup of butter = about 227g (2 sticks)
1 stick of butter = 113g (in Italy, butter comes in 250g or 125g blocks)
🔥 The Oven: Celsius, Not Fahrenheit
Italian ovens use Celsius (°C). At first you’ll have to convert temperatures, but you’ll get used to it quickly.
| Celsius (°C) | Fahrenheit (°F) | Italian Description |
|---|---|---|
| 120 °C | 250 °F | Forno molto basso (very low oven) |
| 160 °C | 320 °F | Forno medio-basso (medium-low) |
| 180 °C | 350 °F | Forno moderato (moderate oven) |
| 200 °C | 400 °F | Forno caldo (hot oven – pizza, bread) |
| 220–230 °C | 425–450 °F | Forno molto caldo (very hot – roasting, gratin) |
🛒 At the Supermarket: What to Expect
Here are some everyday differences you’ll notice when shopping in Italy:
- Pasta: Sold in 500g (1.1 lb) packs, not 1 lb.
- Flour: Bags are 1 kg (2.2 lb) or 5 kg, never 5 lb.
- Sugar: Usually in 1 kg packs.
- Olive oil: Bottles of 500 ml, 750 ml, or 1 liter.
- Fruit and vegetables: Priced per kilo. You often weigh them yourself and print a label.
- Meat and fish: Ordered in etti at the counter, or shown in grams on packages.
“Quanto costa al chilo?” = How much per kilogram?
“Mi dia un chilo di mele” = I’d like 1 kilo (2.2 lb) of apples.
“Vorrei 300 grammi di macinato” = I’d like 300g (10.5 oz) of ground meat.
“Due litri di latte, per favore” = Two liters of milk (about half a gallon).

| In Italian | Means | In the U.S. |
|---|---|---|
| “Un etto” | 100g | 3.5 oz |
| “Mezzo chilo” | 500g | 1.1 lb |
| “Un chilo” | 1000g | 2.2 lb |
| “Un litro” | 1000 ml | 33.8 fl oz (4+ cups) |
| “180 gradi” | 180°C | 350°F |
✨ Final Tips for Adapting
- Buy a digital kitchen scale that shows grams and ounces — it costs about €15–20.
- Download a converter app (or just Google “200g in oz”).
- Memorize three key numbers: 1 etto = 3.5 oz, 1 kg = 2.2 lb, 1 liter = 4 cups.
- Don’t be afraid to ask: “Quanto è in grammi?” (How much is that in grams?) is totally normal.
- Practice at the market: Vendors are friendly and will help you out.
Learning the metric system isn’t just about math — it’s about getting into the rhythm of Italian life. After a few months, you’ll start thinking in grams and liters, and when you go back to the U.S., buying meat by the pound will feel strange! 🇮🇹
