This distance calculator is programmed to calculate the distance between two points with the help of longitude and latitude. You can calculate the distance in miles and kilometers for free.

Here’s how you can use our road distance calculator:

- Select the parameter whether Decimal or Degree-minute-second.
- If you have selected Decimal, then input the longitude and latitude of two points.
- But if you have selected Degree-minute-seconds, then enter the degree, minute, and second of longitude and latitude of two points.
- Hit the “
**Calculate**” button.

In the context or geography:

**“The length, space or numeric description between any two points, lines or in easy words range that tells us how far two objects, points or lines are from each other is called distance.”**

The SI unit of distance is **meter(m)**. You can calculate distance in different units which are as follows:

- Centimeters which is 1/100 of a meter.
- Thou or mil unit which is 1/1000 of an inch.
- Line unit which is 1/12 of an inch.
- Inch unit which is equal to 2.45 cm.
- Foot unit which is equal to 12 inches.
- Mile unit which is equal to 5280 feet.
- League unit which is equal to 3 miles.

Now, you do not need to be worried about a particular destination that how far is it from here. There is an equation known as Haversine Formula that is used to calculate distances between places on a great sphere most accurately.

$$ a = (sin(\frac{dlat}{2}))^2 + cos(lat1) * cos(lat2) * (sin(\frac{dlon}{2}))^2 $$

Now, you need to determine the value of c as follows:

$$ c = 2 * tan2(\sqrt(a), \sqrt{\left(1 - a\right)}) $$

After doing so, you can calculate distance with the help of following equation below:

$$ d = R * c $$

Where;

**R** = Radius of the Earth

**R = 6,371km**

**R = 3960.62miles**

Our free online distance finder also uses the same formula to calculate the distance between places up to most accuracy.

If you are traveling, use the gas calculator to find the mileage of the vehicle.

Let us guide you properly how you can find distances between places that are far from each other.

**Step # 01:**

Convert the longitudinal and latitude angles in radians as follows:

$$ Radians = Degrees * \frac{π}{180} $$

**Step # 02:**

Calculate the difference between longitudinal and latitude angles with the help of the following equations:

$$ dlon = lon2 - lon1 $$

$$ dlat = lat2 - lat1 $$

**Step # 03:**

After doing so, input all values in the haversine formula as follows:

$$ a = (sin(\frac{dlat}{2}))^2 + cos(lat1) * cos(lat2) * (sin(\frac{dlon}{2}))^2 $$

**Step # 04:**

Determine the value of c below:

$$ c = 2 * tan2(\sqrt(a), \sqrt{\left(1 - a\right)}) $$

**Step # 05:**

Finally, calculate the distance by using following formula:

$$ d = R * c $$

This is how you can calculate distance between places. Also, you can use our free online driving distance calculator to determine accurate results.

In System International(SI), there are seven basic units which are as follows:

If you want to adopt manual calculations, you may be subject to the use of haversine formula. But the most accurate and instant method is to use an online distance checker for free.

Distance can be considered as the most crucial term in the field of geography. This distance calculator is very beneficial for students and for those who are working in a field where there is a need of unit’s conversions. Also, during the navigation process, air traffic controllers make a broad use of flight distance calculator to estimate the distance up to the destination and also fuel cost.
