Η καταμέτρηση δείχνει την κατανάλωση σε κιλοβατώρες.

Η καταμέτρηση is the subject of the sentence, so it is in the nominative case.

• η = the (feminine singular, nominative)
• καταμέτρηση = counting, reading, tally, measurement/recording depending on context

In this sentence, it means something like the reading or the recorded measurement.

Because it is the thing that does the action (shows), Greek uses the nominative here.

Because the two nouns have different jobs in the sentence.

• η καταμέτρηση = the subject, so it is in the nominative
• την κατανάλωση = the direct object, so it is in the accusative

Greek changes the definite article depending on case:

For feminine singular:

• nominative: η
• accusative: την

So:

• η καταμέτρηση = the reading (subject)
• την κατανάλωση = the consumption (object)

This is one of the most important patterns in Greek sentence structure.

Δείχνει is the 3rd person singular present tense of δείχνω, meaning to show or to indicate.

So δείχνει means:

• it shows
• it indicates

Since η καταμέτρηση is singular, the verb is also singular:

• Η καταμέτρηση δείχνει... = The reading shows...

Because the Greek sentence is expressing the idea that the reading or meter value indicates the amount consumed.

So the logic is:

• The reading shows the consumption
• not The reading is the consumption

Greek often uses δείχνω in practical, technical, and everyday contexts for screens, meters, instruments, numbers, and displays:

• Το ρολόι δείχνει 5. = The clock shows 5.
• Το θερμόμετρο δείχνει 30 βαθμούς. = The thermometer shows 30 degrees.

So here, δείχνει is very natural.

They are related, but not always identical.

• μέτρηση = measurement
• καταμέτρηση = counting, recording, tallying, a registered reading

In utility or technical contexts, καταμέτρηση often suggests an official or recorded meter reading.

So in this sentence, η καταμέτρηση is likely something like:

• the reading
• the meter reading
• the recorded measurement

It sounds a bit more formal or technical than μέτρηση.

Because it is the direct object of δείχνει.

The sentence structure is:

• Η καταμέτρηση = subject
• δείχνει = verb
• την κατανάλωση = object

In Greek, direct objects normally take the accusative case.

So:

• nominative: η κατανάλωση
• accusative: την κατανάλωση

That is why the article changes from η to την, while the noun itself stays the same in this case.

Σε κιλοβατώρες means in kilowatt-hours.

Here σε is used to express the unit of measurement.

So the phrase means:

• measured in kilowatt-hours
• expressed in kilowatt-hours

This is very common in Greek:

• σε ευρώ = in euros
• σε μέτρα = in meters
• σε λίτρα = in liters

So την κατανάλωση σε κιλοβατώρες = the consumption in kilowatt-hours.

Because kilowatt-hours are countable units, and Greek normally uses the plural when talking about a quantity measured in those units.

So:

• μία κιλοβατώρα = one kilowatt-hour
• κιλοβατώρες = kilowatt-hours

Even when no specific number is given, Greek often uses the plural for the unit in a phrase like this:

• σε κιλοβατώρες = in kilowatt-hours

That matches English quite closely.

Because after σε, when Greek is giving a unit, the article is often omitted.

So:

• σε κιλοβατώρες = in kilowatt-hours

This sounds natural and general.

If you added the article, it would usually sound more specific or less natural here. In technical phrasing, Greek commonly uses:

• σε ευρώ
• σε μέτρα
• σε λίτρα
• σε κιλοβατώρες

with no article.

Yes. Greek word order is more flexible than English because case endings and articles show the grammatical roles.

The neutral, straightforward order here is:

• Η καταμέτρηση δείχνει την κατανάλωση σε κιλοβατώρες.

But Greek could rearrange parts for emphasis, for example:

• Την κατανάλωση σε κιλοβατώρες δείχνει η καταμέτρηση.

This would emphasize the consumption in kilowatt-hours.

Still, the original order is the most natural if you are just stating information plainly.

A simple pronunciation guide:

• Η = ee
• καταμέτρηση = ka-ta-ME-tree-see
• δείχνει = roughly THEE-khnee or DHEE-khnee, depending on accent and how closely you imitate Greek sounds
• την = teen
• κατανάλωση = ka-ta-NA-lo-see
• σε = seh
• κιλοβατώρες = kee-lo-va-TO-res

A rough full reading:

ee ka-ta-ME-tree-see THEE-khnee teen ka-ta-NA-lo-see seh kee-lo-va-TO-res

A few stress points:

• καταμέτρηση
• δείχνει
• κατανάλωση
• κιλοβατώρες

Yes, both are feminine singular nouns here.

You can tell from the articles:

• η καταμέτρηση
• την κατανάλωση

Also, many Greek nouns ending in:

• -ηση
• -ωση

are feminine.

Examples:

• η χρήση = use
• η μέτρηση = measurement
• η κατανάλωση = consumption
• η ενημέρωση = update/information

This is a useful pattern for learners.

You can, but it may sound a little unnatural.

Word-for-word, it is roughly:

• The reading shows the consumption in kilowatt-hours.

Depending on context, more natural English might be:

• The reading shows consumption in kilowatt-hours.
• The meter reading shows the consumption in kilowatt-hours.
• The reading indicates usage in kilowatt-hours.

So the Greek structure is straightforward, but the best English translation may vary depending on the situation.
