Gray Code to Decimal Converter is used to convert a Gray Code number into Decimal format. Use the Gray Code Converter tool to convert between any number base and gray code.

Background Information

A Gray Code can be converted to Decimal in three steps:-

- Take the first bit of the gray code input and write it to the output
- Repeat the following steps until you reach the end of the input
- Take the second bit of the input and XOR it to the last bit of the output
- Write this result to the output. So,
`0 + 0 = 0`

,`0 + 1 = 1`

,`1 + 0 = 1`

and`1 + 1 = 0`

. - Convert the binary output to decimal

Let's say your Gray Code value is `11111011`

and you want to convert it to it's Decimal form.

**Step 1:**Take the first bit of the gray code input and write it to the output. Output is**1****Step 2:**Repeat the steps below until you reach the end of the input- Take the second bit of the input and XOR it to the last bit of the output.
`1 + 1 = 0`

- Write the result to the output. Output:
`1`

**0** - Take the third bit of the input and XOR it to the last bit of the output.
`1 + 0 = 1`

- Write the result to the output. Output:
`10`

**1** - Take the fourth bit of the input and XOR it to the last bit of the output.
`1 + 1 = 0`

- Write the result to the output. Output:
`101`

**0** - Take the fifth bit of the input and XOR it to the last bit of the output.
`1 + 0 = 1`

- Write the result to the output. Output:
`1010`

**1** - Take the sixth bit of the input and XOR it to the last bit of the output.
`0 + 1 = 1`

- Write the result to the output. Output:
`10101`

**1** - Take the seventh bit of the input and XOR it to the last bit of the output.
`1 + 1 = 0`

- Write the result to the output. Output:
`101011`

**0** - Take the eighth (last) bit of the input and XOR it to the last bit of the output.
`1 + 0 = 1`

- Write the result to the output. Output:
`1010110`

**1**

- Take the second bit of the input and XOR it to the last bit of the output.
**Step 3:**So, our binary result is:`10101101`

**Step 4:**Convert the binary output to decimal. So,`10101101`

becomes`173`
