Engineering functions for number conversions in various bases
Excel Function OCT2BIN
The OCT2BIN() function is used to convert octal number to binary notation.
The octal number has a base value of 8 and binary has a base value of 2.
This function is also most often used in digital computation.
| Octal | Binary | Formula |
| 45 | 100101 | =OCT2BIN(L4) |
| 76 | 111110 | =OCT2BIN(L5) |
| 4 | 100 | =OCT2BIN(L6) |
| 7 | 111 | =OCT2BIN(L7) |
| 23 | 10011 | =OCT2BIN(L8) |
| 8 | #NUM! | =OCT2BIN(L9) |
As seen above, the number 8 results in error since octal has numbers from 0 to 7 only.
Excel Function OCT2DEC
The OCT2DEC() function is used to calculate decimal value of a given octal number.
This function is used to convert the octal number into base-10 notation.
| Octal | Decimal | Formula |
| 45 | 37 | =OCT2DEC(L18) |
| 76 | 62 | =OCT2DEC(L19) |
| 4 | 4 | =OCT2DEC(L20) |
| 7 | 7 | =OCT2DEC(L21) |
| 23 | 19 | =OCT2DEC(L22) |
| 65 | 53 | =OCT2DEC(L23) |
Excel Function OCT2HEX
The OCT2HEX() function is used to convert octal number to hexadecimal form.
This function converts the number to base-16 form.
This function is most used with microprocessor problems.
| Octal | Hex | Formula |
| 45 | 25 | =OCT2HEX(L30) |
| 76 | 3E | =OCT2HEX(L31) |
| 4 | 4 | =OCT2HEX(L32) |
| 7 | 7 | =OCT2HEX(L33) |
| 23 | 13 | =OCT2HEX(L34) |
| 65 | 35 | =OCT2HEX(L35) |
Excel Function HEX2BIN
The HEX2BIN() function is used to convert hexadecimal number to binary notation.
The hexadecimal number has a base value of 16 and binary has a base value of 2.

| 25 | 100101 | =HEX2BIN(L44) |
| 3E | 111110 | =HEX2BIN(L45) |
| 4 | 100 | =HEX2BIN(L46) |
| 7 | 111 | =HEX2BIN(L47) |
| 13 | 10011 | =HEX2BIN(L48) |
| 35 | 110101 | =HEX2BIN(L49) |
Excel Function HEX2DEC
The HEX2DEC() function is used to calculate decimal value of a given hexadecimal number.
This function is used to convert the hexadecimal number into base-10 notation.
| Hex | Decimal | Formula |
| 25 | 37 | =HEX2DEC(L57) |
| 3E | 62 | =HEX2DEC(L58) |
| 4 | 4 | =HEX2DEC(L59) |
