-# Convert Binary to Decimal
+### Binary Number System
 
-This tool converts a binary number to a decimal number.
+The binary number system is a base-2 number system. It uses only two symbols: 0 and 1. The binary number system is used in computers and other digital devices.
 
-## Example
+### Decimal Number System
 
-```text
-Binary: 1001
-Decimal: 9
-```
+The decimal number system is a base-10 number system. It uses ten symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The decimal number system is used in everyday life.
 
-## How to convert binary to decimal
+### Conversion
 
-To convert a binary number to a decimal number, you need to multiply each digit by 2 raised to the power of its position in the number. Then, you need to add all the results together.
+The conversion from binary to decimal is done by multiplying each digit by the power of 2. The power of 2 is the position of the digit from the right. The first digit is multiplied by 2^0, the second digit is multiplied by 2^1, the third digit is multiplied by 2^2, and so on.
 
-For example, let's convert the binary number `1001` to a decimal number.
+For example, the binary number 1011 is converted to decimal as follows:
 
 ```text
-1 * 2^3 + 0 * 2^2 + 0 * 2^1 + 1 * 2^0 = 8 + 0 + 0 + 1 = 9
+1 * 2^0 + 0 * 2^1 + 1 * 2^2 + 1 * 2^3 = 11
 ```

+### Celsius
 
-This tool converts a temperature in Celsius to a temperature in Fahrenheit.
+The Celsius scale is a temperature scale based on 0 degrees for the freezing point of water and 100 degrees for the boiling point of water. The Celsius scale is used in most of the world.
 
-## Example
+### Fahrenheit
 
-```text

+The Fahrenheit scale is a temperature scale based on 32 degrees for the freezing point of water and 212 degrees for the boiling point of water. The Fahrenheit scale is used in the United States.
 
-## How to convert Celsius to Fahrenheit
+### Conversion
 
-To convert a temperature in Celsius to a temperature in Fahrenheit, you need to multiply the temperature in Celsius by 1.8 and add 32.
+The conversion from Celsius to Fahrenheit is done by multiplying the Celsius temperature by 9/5 and adding 32.
 
-For example, let's convert the temperature `-40` Celsius to a temperature in Fahrenheit.
+For example, the Celsius temperature 0 is converted to Fahrenheit as follows:
 
 ```text
--40 * 1.8 + 32 = -40 * 1.8 + 32 = -40
+0 * 9/5 + 32 = 32
