Pesaron el equipaje facturado en la báscula.

Pesaron is the preterite (simple past) of pesar, in the third person plural.

So it literally means they weighed.

In this sentence, the action is seen as a completed event in the past: the luggage was weighed, and that action is finished.

pesar = to weigh
pesaron = they weighed

It often does not refer to a specific named group.

In Spanish, the third person plural is very commonly used when the speaker does not say exactly who did the action, but the people are understood from context. Here, it would probably mean something like:

• airport staff
• the airline employees
• the people at check-in

So Pesaron el equipaje facturado... can feel like:

• They weighed the checked luggage
• or more naturally in English, The checked luggage was weighed

Spanish often uses this structure instead of a passive.

Because equipaje is usually an uncountable / collective noun, much like luggage or baggage in English.

Even if there are several bags, Spanish can still say el equipaje as one whole category.

That is why the sentence has:

• el equipaje
• facturado (singular masculine, agreeing with equipaje)

If you wanted to talk about individual items, you might use:

• las maletas = the suitcases
• las piezas de equipaje = the pieces of luggage

Spanish uses the definite article much more often than English.

Here, el does not mean that the noun is especially formal or unusual; it just marks the luggage as a specific thing in the situation: the checked luggage.

English sometimes drops the article more easily, but Spanish usually keeps it:

• Pesaron el equipaje facturado
• literally: They weighed the checked luggage

Without el, the phrase would sound unnatural in this sentence.

Here facturado means checked in or checked, as in checked luggage.

It comes from the verb facturar, which in travel contexts in Spain can mean:

• to check in luggage
• to consign luggage for transport

So:

• equipaje facturado = checked luggage
• equipaje de mano = hand luggage / carry-on luggage

Be careful: in other contexts, facturar can also relate to invoicing or billing, so the meaning depends on context.

In Spanish, adjectives and participles often come after the noun.

So equipaje facturado is the normal order for checked luggage.

This is especially common when the word after the noun helps classify or specify the noun:

• equipaje facturado = checked luggage
• equipaje perdido = lost luggage
• puerta principal = main door

Putting facturado after the noun sounds natural and standard here.

Spanish often uses en where English would use on, especially with places, surfaces, or devices when the idea is in/at/on that location.

So:

• en la báscula = on the scale

This is just normal Spanish usage. You do not usually say sobre la báscula here.

So even though the English translation uses on, Spanish prefers en.

Both relate to weighing, but báscula is the more natural word here.

In Spain:

• báscula usually means a weighing scale, especially a practical one used for luggage, people, or heavier items
• balanza often refers to a balance or a scale in a more general, technical, or sometimes commercial sense

At an airport check-in desk, báscula sounds very natural.

So en la báscula is exactly what you would expect in this context.

Yes. Spanish has other ways to express the same idea, for example:

• El equipaje facturado fue pesado en la báscula.
• Se pesó el equipaje facturado en la báscula.

But Pesaron el equipaje facturado en la báscula is very natural because Spanish often prefers:

• an unspecified they
• or a se construction

instead of a formal passive.

So the original sentence is probably the most everyday-sounding version.

No, Spanish word order is fairly flexible, though the original order is very natural.

The sentence is:

• Pesaron el equipaje facturado en la báscula.

This is a normal pattern: verb + object + place

You could also hear:

• En la báscula pesaron el equipaje facturado.

That gives more emphasis to where the action happened.

So the original version is the neutral, straightforward one, but other orders are possible depending on focus.
