Why is the height of sea level on the railway station board?

in #tech6 years ago

Every time we travel from Indian Railways, we get to know something new about it every time. The city is big or small, some things appear every time on every platform. Like the voice of tea-tea people. People sitting in the name of waiting at the station and the police Apart from this, the particular thing that is seen at the station is yellow information board to identify the station.


The station is big or small, everywhere you will see this yellow board. On which city's name is written in Hindi, English and many times in Urdu. Something else is written under the name of the station. If you have paid attention, you will have to show that on this board the height of the city's sea level is also mentioned. But have you ever wondered why it is written ..?

This is real reason

You must know that the world is round. In order to measure the world at a uniform height, scientists needed a point that looked the same. So sea is perfect in this case. Because sea water remains the same. Hence the height of sea level is written. But what is the use of writing this? What do the drivers and guard do

This is work

Actually, it is not necessary for passengers it is need for guards and drivers. It is used for measuring. As we know that the Earth is round. In order to measure, scientists need such a level that they are the same. For this, there is no better option than sea and nothing can be done.
