Quantities, Measurements, and Counting

When you order two beers or buy three kilos of flour, German does something English never does: it keeps the unit noun singular after a number, and it attaches the substance directly, with no word for "of." So you say zwei Glas Bier (literally "two glass beer") and drei Kilo Mehl ("three kilo flour"). This page teaches the singular-unit rule, the feminine exception that breaks it, the no-of construction, and the famous near-twins ein paar and ein Paar. These are everyday-survival patterns — you'll use them every time you shop, order, or cook.

The Core Rule: Masculine and Neuter Units Stay Singular

This is the headline fact, and it surprises every English speaker. When a masculine or neuter measure or unit noun follows a number, it does not take a plural ending. It stays in its bare singular form, no matter how many there are.

German	Literal	English
zwei Glas Bier	two glass beer	two beers / two glasses of beer
drei Kilo Mehl	three kilo flour	three kilos of flour
fünf Stück Kuchen	five piece cake	five pieces of cake
zwei Pfund Tomaten	two pound tomatoes	two pounds of tomatoes (1 Pfund = 500g)
hundert Gramm Käse	hundred gram cheese	a hundred grams of cheese
drei Meter Stoff	three metre fabric	three metres of fabric
fünf Euro	five euro	five euros
zehn Grad	ten degree	ten degrees

The logic: these nouns are functioning as units of measurement, not as countable objects. A Glas here isn't a physical glass you could break — it's a unit ("a glassful"). German marks this measuring role by freezing the noun in the singular. Money and degrees work the same way: fünf Euro, zehn Grad, dreißig Cent.

Zwei Glas Bier, bitte — und für ihn ein Wasser.

Two beers, please — and a water for him.

Ich hätte gern drei Kilo Kartoffeln und ein Pfund Möhren.

I'd like three kilos of potatoes and a pound of carrots.

Heute werden es bestimmt dreißig Grad.

It's definitely going to hit thirty degrees today.

💡

Contrast the measure reading with the object reading. Zwei Glas Bier means "two servings of beer." But if you literally mean two physical drinking glasses as objects, you'd say zwei Gläser (plural). The singular form is a signal: "I'm measuring, not counting containers." This is exactly why a waiter hears zwei Glas Bier as an order for two beers.

The Feminine Exception

The singular-unit rule applies to masculine and neuter units. Feminine units behave normally and do take the plural. The most common ones are die Tasse (cup), die Flasche (bottle), die Dose (can), die Schachtel (box/pack).

Masculine/Neuter (singular)	Feminine (plural)
zwei Glas Wein	zwei Flaschen Wein
drei Stück Zucker	drei Tassen Kaffee
ein Sack Mehl	zwei Dosen Suppe

Wir haben drei Tassen Kaffee getrunken und immer noch keinen klaren Kopf.

We've drunk three cups of coffee and still don't have a clear head.

Kannst du zwei Flaschen Wasser mitbringen?

Can you bring two bottles of water?

There's no deep semantic reason for the split — it's a grammatical fact you memorise by gender. A useful shortcut: the high-frequency exceptions are nearly all feminine container words ending in -e (Tasse, Flasche, Dose, Schachtel, Kanne). If the unit is feminine, pluralize it.

No "of": the Substance Attaches Directly

English glues the substance on with "of": a cup *of coffee, a kilo **of flour. German uses *nothing at all — the substance noun simply follows the unit, in the same case as the whole phrase (apposition).

eine Tasse Kaffee

a cup of coffee (literally 'a cup coffee')

ein Glas Wasser, bitte

a glass of water, please

Möchtest du ein Stück Kuchen?

Would you like a piece of cake?

Inserting von ("of") here is one of the most common English-speaker errors and always sounds wrong. Von does appear in genitive-style partitive phrases (einer von uns = one of us), but not between a unit and its substance.

💡

Picture the unit and the substance as standing in apposition — two nouns side by side describing one quantity, like die Stadt Berlin ("the city Berlin," no "of"). Eine Tasse Kaffee is "a cup, [namely] coffee." There is simply no slot for an English-style "of."

ein paar vs ein Paar

These look identical in speech but mean completely different things — distinguished only by capitalization in writing:

ein paar (lowercase, indeclinable) = a few, some. A vague small quantity. From the same root as English "a couple," but it has lost the precise "two" meaning.
ein Paar (capital, a neuter noun das Paar) = a pair, exactly two that belong together. ein Paar Schuhe (a pair of shoes), ein Paar Socken, ein verliebtes Paar (a couple in love).

Ich brauche nur noch ein paar Minuten.

I just need a few more minutes.

Ich habe mir ein Paar neue Schuhe gekauft.

I bought myself a (new) pair of shoes.

Wir laden noch ein paar Freunde ein.

We're inviting a few more friends.

The test: can you replace it with "some/several" (then it's ein paar) or with "two that go together" (then it's ein Paar)? Ein Paar Handschuhe is two matching gloves; ein paar Handschuhe is several gloves lying around.

More Counting Words

A few more high-frequency quantity expressions:

ein Dutzend — a dozen (twelve): ein Dutzend Eier. Like other neuter units, stays singular: zwei Dutzend Eier.
eine Menge / jede Menge — a lot of: eine Menge Arbeit (a lot of work).
viel
- mass noun (no plural), viele
  - count noun (plural): viel Geld (much money) vs viele Leute (many people).
Stück for counting individual items at a shop: Ich nehme fünf Stück (I'll take five [of them]).
je / pro for "each / per": zwei Euro je Stück / pro Person (two euros each / per person).

Für den Kuchen brauchen wir ein Dutzend Eier.

We need a dozen eggs for the cake.

Die Erdbeeren kosten drei Euro pro Schale.

The strawberries cost three euros per punnet.

Common Mistakes

❌ Zwei Gläser Bier, bitte. (als Bestellung)

Incorrect when ordering — the measure unit Glas stays singular.

✅ Zwei Glas Bier, bitte.

Two beers, please — Glas singular as a measure.

❌ eine Tasse von Kaffee

Incorrect — German uses no 'of' between unit and substance.

✅ eine Tasse Kaffee

A cup of coffee.

❌ drei Kilos Mehl

Incorrect — Kilo stays singular after a number.

✅ drei Kilo Mehl

Three kilos of flour.

❌ Ich habe ein paar Schuhe gekauft. (für genau zwei)

Incorrect for 'a pair' — ein paar means 'a few', not 'a matching two'.

✅ Ich habe ein Paar Schuhe gekauft.

I bought a pair of shoes (the matching two).

❌ zwei Tasse Kaffee

Incorrect — feminine Tasse DOES pluralize.

✅ zwei Tassen Kaffee

Two cups of coffee.

Key Takeaways

Masculine and neuter measure units stay singular after a number: zwei Glas, drei Kilo, fünf Euro, zehn Grad.
Feminine units pluralize normally: zwei Tassen, drei Flaschen.
The substance attaches directly, with no von: eine Tasse Kaffee.
ein paar = a few; ein Paar = a matching pair (exactly two) — distinguished by capitalization.
Stück, Dutzend, je/pro round out the everyday counting vocabulary.
