ETA Full Form

What is the Full Form of ETA in English?

The Full Form of ETA in English is the Estimated Time of Arrival or Expected Time of Arrival. ETA refers to the time required or expected for an object or entity to complete its journey. The object can be anything from a train to a courier to a book or project. 

A little About the Usage of ETA:

The term ETA is used to refer to the date and time of the arrival of some entity or the completion of something. The time mentioned in the format of hours and minutes. The most common use of ETA is seen to be in the movement of public transports and couriers. The ETA of the transports is calculated depending on the static time table, speed, and the traffic they can face on their journey.  ETA is coupled with the Estimated Time of Departure that is the ETD of the particular thing to refer to the time of the journey needed. 

How Do You Calculate ETA?

The ETA of an object is calculated with the help of distance and speed. 

So, to formulate, we can say ETA= total distance /speed of travel

We can look at some example:

Suppose you have ordered a beautiful dress online. Now you would want to know when you will get to see that dress in front of you. The delivery app will give you an ETA of your purchase. This ETA is the expected date on which the dress will be delivered to you. 

Now suppose, you have a trip planned to Delhi, from Mumbai, via train. Here also you will get an ETA. This ETA refers to the time of arrival of the train at the Delhi station, from the time of departure from Mumbai station. Here, the ETA will be calculated by the distance between the two stations and the speed of the time. Remember, that here the ETA will not include any extra amount of time needed for the train to cover due to some unwanted situations. The additional amount of time will be an addition to the actual ETA. 

Now, let us discuss some inanimate things' ETA. Suppose you are working on a project of a logo design project in your office. Now your boss might want to know when you will finish your task. Here, naturally, you cannot have a distance to measure. So, you will use your experience of designing a logo along with the time you take to complete such a task. And voila, you will be able to tell the ETA of your task to your boss.
