Convert from Octal (Base 8) to Decimal (Base 10)

¿How to convert from Octal (Base 8) to Decimal (Base 10)?

Note: To convert a number from octal (base 8) to any other base, we first need to convert the octal value to decimal (base 10). To do this, follow these steps:

1. Identify each digit of the octal number.
2. Calculate the position of each digit. Start from the rightmost digit, which will have a position of 0. Each digit to the left will have an incremental position of 1 (1, 2, 3, etc.).
3. Calculate the decimal value of each digit by multiplying it by the base (8) raised to the position of the digit. For example: digit * 8^position.
4. Add up the values obtained in the previous step to get the equivalent decimal number.

Applying these steps to the octal number 237:

1. 2, 3, and 7 are the digits.
2. From right to left, the positions are 0, 1, and 2.
3. 2 * 8^2 = 128; 3 * 8^1 = 24; 7 * 8^0 = 7.
4. 128 + 24 + 7 = 159 decimal

Therefore, 237 octal = 159 decimal.
