कृपया पार्सल तौलें।

कृपया means please, but it is quite formal and is especially common in:

• written instructions
• announcements
• customer-service language
• polite official speech

In everyday conversation, people often use other polite strategies instead of कृपया, such as:

• ज़रा पार्सल तौलें। = Please weigh the parcel.
• पार्सल तौल दीजिए। = Please weigh the parcel.

So कृपया पार्सल तौलें। is correct, but it sounds more formal than casual everyday speech.

Hindi often omits the subject when it is understood from context.

In कृपया पार्सल तौलें।, the implied subject is आप:

• (आप) कृपया पार्सल तौलें।

Hindi does this very naturally, especially in commands and requests. Since the verb form तौलें already shows a polite command, the listener understands that the speaker means you.

तौलें is the verb form meaning weigh in the sense of a polite request or command.

It comes from the verb:

• तौलना = to weigh

So:

• तौलें = weigh / please weigh

In this sentence, it is telling someone politely to perform the action of weighing the parcel.

Here, -ें is not mainly showing plural in the English sense. In this sentence, it is part of a polite imperative/subjunctive-style form used with आप.

So तौलें is the kind of form used for:

• polite commands
• respectful requests
• formal instructions

Compare:

• तौल — very direct, used with तू
• तौलो — less formal, used with तुम
• तौलें — polite/respectful, used with आप

So the ending -ें here is best understood as a marker of politeness/respect, not just plurality.

It is formal and polite.

There are two main reasons:

• कृपया is formal
• तौलें is the polite verb form

This sentence would fit situations like:

• at a post office
• at a shipping counter
• in written instructions
• in customer service

A more conversational version might be:

• पार्सल तौल दीजिए।
• ज़रा पार्सल तौल दीजिए।

These often sound more natural in spoken Hindi.

पार्सल is a borrowed word from English parcel. Hindi uses many loanwords like this.

So:

• पार्सल = parcel / package

This is very normal in modern Hindi. Especially for practical everyday items, Hindi often uses English-derived words alongside native vocabulary.

Because पार्सल is the direct object of the verb, and in Hindi, direct objects often appear without any extra marking, especially when they are inanimate.

So:

• पार्सल तौलें। = Weigh the parcel.

Hindi does not need an article like the, and it also does not have to add को here.

That is why पार्सल simply stays as पार्सल.

In Hindi, को is often used with:

• people
• animate beings
• specific or affected objects in some contexts

But with many inanimate direct objects, especially in straightforward instructions, को is often omitted.

So:

• पार्सल तौलें। sounds natural.
• पार्सल को तौलें। is possible, but it sounds more marked or emphatic and is less neutral in this simple instruction.

For a learner, the best default here is:

• पार्सल तौलें।

A simple learner-friendly pronunciation guide is:

• krip-ya paar-sal tau-len

A few notes:

• कृपया is often pronounced roughly like krip-ya
• पार्सल has a long aa sound at the start: paar-sal
• तौलें has the au sound like cow, followed by len

So a rough full pronunciation is:

• krip-ya paar-sal tau-len

Learners may notice forms related to तोलना / तौलना in dictionaries or usage. In standard usage for to weigh, तौलना and its form तौलें are the expected forms in this sentence.

So for this sentence, use:

• कृपया पार्सल तौलें।

That is the safest and most standard choice.

A very natural spoken version would be:

• पार्सल तौल दीजिए।

Even more polite/softer:

• ज़रा पार्सल tौल दीजिए।

Why this sounds natural:

• दीजिए is commonly used to soften requests
• ज़रा makes the request gentler
• everyday spoken Hindi often prefers this style over कृपया + verb

So:

• कृपया पार्सल तौलें। = correct, formal
• पार्सल तौल दीजिए। = very natural spoken polite Hindi

Functionally, it is an imperative/request: the speaker is telling someone to do something.

Grammatically, the form तौलें is often described as a polite imperative or a form built from the subjunctive pattern used for respectful commands.

For a learner, the important practical point is:

• तौलें = polite weigh
• the whole sentence = Please weigh the parcel

So even if grammar books describe it in different technical ways, its use here is straightforward: it is a polite command/request.
