Standard meridian is an imaginary line which passes through Mirzapur ,Uttar Pradesh . It lies almost at 82.30'E. It determines the time over the India. As there is a time lag of 2 hours between estern and western point of India.

Standard meridian is useful for a country because it shows and fixes a particular time for the country. A country may have many longitudes in between and there is a time gap of 4 minutes between each longitude. Here are some of the points which shows the importance oc standard meridian of India : 1.

Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude.

The 180th meridian or antimeridian is the meridian 180° both east and west of the Prime Meridian, with which it forms a great circle dividing the earth into the Western and Eastern Hemispheres.

The primary unit in which longitude and latitude are given is degrees (°). There are 360° of longitude (180° E ↔ 180° W) and 180° of latitude (90° N ↔ 90° S). Each degree can be broken into 60 minutes ('). Each minute can be divided into 60 seconds (”).

What is the difference between a central meridian and the Prime Meridian? The Prime Meridian is the longitude line on earth defined as zero, and it runs through Greenwich, England. A central meridian is the center of a map projection where x = 0, and may be any longitude line.

The prime meridian, or 0 degrees longitude, and the International Date Line, 180 degrees longitude, divide the Earth into Eastern and Western hemispheres.

Formula to Convert Meters – Kilometers The conversion formula for this exchange in units of measurements is m / 1000 = km and is an accurate formula that is used by this online calculator. For example, 50m = 0.05km and 12m = 0.012km.

Each of these longitudes is called a degree. The 0 degree longitude passing through Greenwich, near London, is considered as standard and the time of all other time zones are calculated accordingly. The time difference between each longitude (each degree) is 4 minutes.

The standard deviation (abbreviated s or SD) is calculated according to the following formula: That is, calculate the deviation from the mean for each point, square those results, sum them, divide by the number of points minus one, and finally take the square root.
