What is the standard meridian f Pakistan and why?

The standard meridian of Pakistan is 70 degrees east. This is because the country is located in the northern hemisphere and mostly lies between 61 degrees east and 77 degrees east longitude. The 70th meridian east passes through the middle of the country, making it the most suitable choice for the standard meridian.

Having a standard meridian is important because it allows for a consistent and accurate measurement of time within a country. It also serves as a reference point for determining longitude and helps in creating maps and charts.
