“Is used,” “has been used,” and “was used” are all grammatically correct, but they describe actions in different ways. The main difference is tense and if you are focusing on a present fact, a past action, or an action that began or occurred in the past and is relevant to the present.
Understanding these forms is especially useful in academic, technical, professional, and everyday English.
Quick Answer
Is used = describes a present or general use.
This tool is used to analyze data.
Has been used = describes something that has been used in the past, with a connection to the present.
This tool has been used for many years.
Was used = describes something that was used at a particular time or during a completed past situation.

Easy Rule

Is Used
Is used is the passive form of the present simple.
We use it when something is generally used for a particular purpose or when describing a current fact, rule, method, or practice.
Examples
English is used around the world.
This machine is used to produce electricity.
Water is used for many purposes.
This word is used in formal English.
The software is used by thousands of people.
These sentences describe general or current facts, rather than one specific completed event.
Common Pattern
Subject + is used + to + verb
This tool is used to measure temperature.
Or:
Subject + is used + for + noun/gerund
This tool is used for measuring temperature.
Has Been Used
Has been used is the present perfect passive.
It describes something that happened in the past but has a connection to the present. The exact time may be unknown, unimportant, or may extend up to the present.
Examples
This method has been used for decades.
The software has been used by researchers around the world.
This technique has been used successfully in several studies.
The word has been used in English for centuries.
The equipment has been used several times.
The focus is not necessarily on one particular past moment. Instead, the speaker is emphasizing the experience, history, or present relevance of the action.
Was Used
Was used is the simple past passive.
Use it when the action happened in the past and is viewed as finished or connected to a specific past event or period.
Examples
The machine was used yesterday.
This method was used during the experiment.
The car was used by the previous owner.
The term was used in the article.

Compare These Three Sentences
Consider:
This software is used by researchers.
This means researchers generally use the software. It is a current or general fact.
This software has been used by researchers.
This tells us that researchers have used it at some point or over a period of time. The past use is relevant to the present.
This software was used by researchers.
This refers to a completed past situation. The context may tell us when or during what event it was used.
Example With Time
Time expressions can make the difference much clearer.
Is Used
This system is used every day.
This describes a regular or current practice.
Has Been Used
This system has been used since 2020.
The use began in the past and continues or remains relevant now.
Was Used
This system was used from 2020 to 2023.
The period is finished.
“Has Been Used” vs “Was Used”
This is one of the most important distinctions.
Compare:
The method was used in 2022.
The sentence refers to a specific completed past period.
The method has been used since 2022.
The sentence connects the past with the present. It may mean the method continues to be used.
Another example:
The car was used by John.
This describes a completed past situation.
The car has been used by John.
This tells us that John has used the car at some point, without necessarily specifying when.
“Is Used” vs “Has Been Used”
Compare:
This word is used in formal English.
This is a general statement about current usage.
This word has been used in formal English for centuries.
This emphasizes its history of usage.
The first focuses on what is true now.
The second focuses on what has happened over time.
“Is Used” vs “Was Used”
Compare:
This machine is used to make paper.
This describes its normal or current function.
This machine was used to make paper.
This suggests the machine had that function in a particular past situation or period.
For example:
The old machine was used to make paper before it was replaced.
Here, the use is clearly finished.
Passive Voice
All three expressions use the passive voice.
Active
People use this method.
Passive
This method is used by people.
For the other forms:
Active: Researchers have used the method.
Passive: The method has been used by researchers.
Active: Researchers used the method.
Passive: The method was used by researchers.
The passive voice puts the focus on the thing being used, rather than the person doing the action.
Common Mistakes
Using “was used” for a general fact
❌ This tool was used to measure temperature.
If you’re describing its general function, this may be misleading.
✅ This tool is used to measure temperature.
But if you’re talking about a particular past experiment:
✅ This tool was used to measure the temperature during the experiment.
Using “has been used” with a finished past time
A specific finished time normally calls for the simple past.
❌ The method has been used in 2020.
✅ The method was used in 2020.
But:
✅ The method has been used since 2020.
Using “is used” for a completed past event
❌ The machine is used yesterday.
✅ The machine was used yesterday.
The word yesterday clearly refers to a completed past time.
