Calculate Ranges With A Mil-Dot

As mentioned in the opening, a mil-dot rifle scope applies optics. It makes it simple and easy to calculate the distance from the range to the target.

In the past, people used them for submarines when traveling. Along with the continuous progress and development of modern science and technology, they are smaller and used for guns. Typically, guns are available in the military, and rifles are famous for entertainment.

Here are some methods you can apply to calculate distances with a mil-dot rifle scope quickly.




Section 1: In riflescope equipped with Binoculars and periscope. However, they are not similar to the mile dot rifle scope. Although, they are to measure some angle. But, reality shows that 10Mils is not just one. This design feature may be more suitable for sharpshooters.

Section 2: A Mile is 1-6,175 of a circle. It was in the calculation of the US military. Then, they count them as 1-6283 of a circle, instead of 1-6400 of a circle as before.

In addition, the Russian army counts as 1-6000 of a circle. Thus, it can be that each country has a different way of calculating distance and up to 3% error.

Section 3: When you look at Dots through your lens, you need to know that 1 Mile is the distance between one dot and the next from their center.

Note that Mil is not the distance between the dots. Each bead is 0.2 miles, and the distance between the ones is 0.8 m

Section 4: The distance calculated on the plane behind the cross over variable power range. They will reflect accurately at peak power levels.

Measuring Distance

Section 1: The formula for calculating the distance to a commonly used object:

Distance to object= (Height (or width) of object x 1000) / number of Mils respectively.

For example, an object with a height of 9 feet corresponds to 3 feet. The number of miles that the object traveled is 6 Miles. Thus, according to the formula, the distance to the thing is 3 x 1000/6= 500.

Section 2: The more accurate this distance calculation, the better the shooting process’s later stages. Subsequent (made up by you) errors in spacing are largely unacceptable.

At the same time, you also have some tips when calculating. You should subdivide Dots as much as possible for even more accuracy; furthermore, the more accurate the estimate of the object size, the greater the success rate.

For example, you are aiming for a target 8 feet (2.67 yards) tall and have the number of 2.8 Mils, so the distance to the target is 953 meters.

If you predict the object is 3 yards instead of 2.67. That way, you’ll be able to deviate from your target by as much as 5 inches.

Another way to calculate the height and width of an object is 1/10 of an inch. At the same time, calculating the interval in one also uses 1/10 of the mile.

However, to have the most accurate answer, the size estimation is fundamental, determining the perfect result.

Section 3: Alternatively, you can also use a calculator if you wish. While many calculations require logical reasoning or are highly complex, you can make good use of the computational speed the calculator offers.

Tips To Follow

It would help if you pocketed the following tips to calculate the most accurate range.

Unify units: If you are using meters as the unit for measuring the height and width of an object, the range needs to be in this unit as well.

  • Mounted scope: The stronger they are mounted, the higher the chance you will lose track of your target after the bullets leave the barrel. Similar to if you give the scope less strong, aiming and tracking the target will be faster and easier, easier.
  • Keep the scope steady: This action will help the accuracy when calculating the distance to the target higher.
  • Uses Dots: They are also available for bullet drop compensation or windage adjustment.
  • Use a high viewfinder: They help calculate the range better, less cumbersome to use.
  • Another formula: Distance (meters) = (25.4 x inches of target)/mile reading.

How Far Is A Mil On A Scope?

A Mil is commonly available in the US Army. Then, the unit of angle is called milliradian.

In the above presentation, the distance from one datacenter to another is Mildot in 1 Mil. Each dot is 0.2 miles, and the distance between the dots is 0.8 m

By convention, about 36 inches is equal to 1 yard. At the same time, you can also understand 3.6 inches at 100 yards.

So, if you know the size of the distant object, be it a person or any other entity, based on the data you already have, you can calculate the distance. It is straightforward when applying the formula above.

How Many Inches Are Miles In Yards?

The answer is 3.6 inches at 100 yards.

What formula is to find the distance when looking through the instrument scope?

As mentioned above, when you have a scope, you use the lens to see the magnitude and size of the object measured in a mile. At the same time, you have the MIl-Dot Range Formula as follows:

Range = Target Height (Yards) x 1,000/ Mil Through Scope

This formula has proven to be helpful. When 1mil corresponds to 36 inches (1 yard) at 1,000 yards. So, when you stand up on a measuring tape on a 1,000-foot-long shooting tape and look through the lens simultaneously, you’ll see it’s exactly one million tall.

What Are The Dots On A Sniper Scope?

The dots are responsible for helping snipers determine range and aim. At the same time, the dots around the target help shooter determine and estimate the range between the object and the gun. Moreover, they can also resolve the wind and moving targets.

BDC (ballistic drop compensators) is similar to a small wheel. They will make it easier for snipers to adjust the scope without touching it. They can adjust up to 1,000 yards and up and down and different directions of the scope.

The above article has provided methods, tips, and notes for you to know how to use mil dots on a rifle scope.

Hopefully, after understanding the above information, you can calculate the most accurate distances with a mil-dot rifle scope.

Good luck on your hunting trips!
