La medición de la potencia está en la factura.

La is the feminine singular definite article, meaning the. It matches medición, which is a feminine singular noun.

• la medición = the measurement
• el libro = the book (masculine)
• las mediciones = the measurements (feminine plural)

In Spanish, articles are used more often than in English, so la sounds natural here.

Both words can relate to measurement, but they are not always used the same way.

• medición usually refers to the act or process of measuring, or a formal measurement reading.
• medida can mean a measurement too, but it often means size, dimension, or measure in a broader sense.

In a technical or utility context, la medición sounds more precise and natural for something like a recorded measurement on a bill.

De la potencia literally means of the power. In Spanish, de is commonly used where English might use a noun-noun combination.

So instead of saying:

• power measurement

Spanish often says:

• medición de la potencia
  literally, measurement of the power

This structure is very common:

• la factura de electricidad = the electricity bill
• el consumo de agua = water consumption
• la velocidad del carro = the car's speed

Potencia usually means power output, electrical power, or capacity, especially in technical contexts.

Depending on context, it could refer to things like:

• contracted electrical power
• power rating
• power measurement

A learner should know that potencia is not always the same as everyday power in English. In utility or engineering language, it often has a specific technical meaning.

Spanish uses estar for location, even when talking about where something is written or found.

So:

• Está en la factura = It is on the bill

You would not normally say es en la factura for location.

A useful rule:

• ser = identity, classification, essential characteristics
• estar = location, condition, temporary states

Examples:

• La oficina está en el centro. = The office is downtown.
• La información está en el documento. = The information is in the document.

The accent mark distinguishes está from esta.

• está = is (from the verb estar)
• esta = this (feminine demonstrative adjective, as in esta factura = this bill)

So the accent is important because it changes the word and its function.

En la factura is the normal way to say something is in/on the bill, meaning it appears as part of the document.

Spanish often uses en where English might say either in or on, depending on context.

• Está en la factura = It is on the bill / in the bill
• Está en el documento = It is in the document
• Está en la página dos = It is on page two

Sobre usually means on top of physically, or about/concerning, so it would not sound right here.

Yes, somewhat. The standard neutral order is:

• La medición de la potencia está en la factura.

You could also say:

• Está en la factura la medición de la potencia.

But that sounds more marked or stylistic, and it is less neutral. For most learners, the original order is the best one to use.

Spanish word order is more flexible than English, but the basic subject + verb + complement order is often the safest choice.

Not with the same meaning. La potencia está medida en la factura would sound odd or at least different. It suggests something like the power is measured on the bill, which is not the same as saying the measurement appears there.

The original sentence means that the measurement is located or shown on the bill:

• La medición de la potencia está en la factura.

If you want to say the bill includes that information, you could also say:

• La factura incluye la medición de la potencia.
• La medición de la potencia aparece en la factura.

It is a noun phrase made of:

• la medición = the head noun
• de la potencia = a prepositional phrase modifying that noun

This is a very common Spanish structure:

• el costo del servicio = the cost of the service
• la lectura del medidor = the meter reading
• el consumo de energía = energy consumption

English often packs nouns together, but Spanish usually connects them with de.

The sentence is grammatically correct, but depending on the real-world context, a native speaker might choose a slightly different wording, especially in utility-bill language. For example:

• La medición de potencia está en la factura.
• La potencia medida aparece en la factura.
• La lectura de la potencia está en la factura.

Whether de la potencia or simply de potencia sounds better can depend on how technical or formal the context is. But for learning purposes, the original sentence is clear and correct.

Medición is pronounced roughly meh-dee-SYON.

The stress falls on the last syllable because of the written accent:

• me-di-ción

Without the accent, Spanish stress rules would place the stress differently. The accent mark tells you exactly where to stress the word.

Also note that ción is a very common ending in Spanish nouns:

• información
• situación
• medición

These usually correspond to English nouns ending in -tion.
