The necessity of converting from one unit to another in physics can be possible in various cases.

If, for example, you cook by the European recipe, then the unit that is normally used is liters, but for this, you have to convert the litters into the cups.

Let’s take another example: you may have to travel to another city or country where the standard unit for travel is miles, where you normally use the kilometer.

In this sense, you need to convert miles into kilometers to feel easy to calculate.

Although these calculations are easily convertible, in this article we will discuss some of the other ways to convert the calculations.

## Why do we have to change unity from one to another?

In physics, we need to convert the unit into different scenarios, just as we need to convert the unit due to the variation in the standard units of different regions.

While we also need to convert different units if we need to calculate something like the speed of a car.

We need these calculations to calculate according to the standard unit that is most commonly used.

Thus, the speed is usually calculated in kilometers per hour, and to do your calculation according to this standard, you need to convert the units.

If we continue with the same example of velocity, if we want to calculate the hours from the minutes, we could easily convert it into hours to do it according to the standard unit.

In physics, the rectification process requires the converter or calculator because the process must convert the alternating voltage into a direct current.

Most consumers using electronic goods are led into direct current with alternating current.

## Why and how to calculate the AC-DC conversion?

Regardless of whether you are calculating the current or voltage, you may need to calculate the AC-DC conversion, which is usually required when performing the rectification process.

For example, you have a transformer that has AC and you will rectify it to convert it into DC.

Now, before or after DC voltage, you may need to know the amount of DC voltage. However, this voltage amount can be known by conversion.

In industries where a suitable transformer is required, the calculation of AC and DC is particularly important during the process of uniformity.

In industry, if the AC voltage is passed through the bridge rectifier, it generates the DC voltage and the manufacturer has to calculate the DC voltage after the conversion.

We can calculate the AC-DC conversion manually using the following formulas:

**DC to AC conversion formula:**

AC = DC / 0,636

**AC to DC Conversion Formula:**

DC = AC 0,636

In the following, however, we have mentioned some of the calculators that help to convert units in physics.

### 1. Ac to Dc by MeraCalculator

This is one of the best online calculators that offers conversion tools in different categories. For physics, it offers more than 50 tools that convert one unit into another.

If you want to convert AC to DC, this tool is a good option, as it does not require registration, but generates the result immediately.

To calculate the AC or DC voltage, you only have to enter the amount in the field of this calculator, which will automatically tell you the result.

### 2. Byjus.com

This is another popular page that has a lot of tools for calculating the conversion of the physical unit. However, this popular page also converts the AC to DC voltage by simply giving it the value of AC or DC voltage.

This calculator is normally used to expect the DC after it has been converted into the rectification process of AC.
