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

Background Information

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

- Convert the input decimal to binary
- Take the first bit of the binary 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 previous bit of the input
- Write this result to the output. So,
`0 + 0 = 0`

,`0 + 1 = 1`

,`1 + 0 = 1`

and`1 + 1 = 0`

.

Let's say your Decimal value is `173`

and you want to convert it to it's Gray Code form.

**Step 1:**Convert the input decimal to binary. So,`173`

becomes`10101101`

**Step 2:**Take the first bit of the binary input and write it to the output. Output is**1****Step 3:**Repeat the steps below until you reach the end of the input- Take the second bit of the input and XOR it to the previous bit of the input.
`1 + 0 = 1`

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

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

- Write the result to the output. Output:
`11`

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

- Write the result to the output. Output:
`111`

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

- Write the result to the output. Output:
`1111`

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

- Write the result to the output. Output:
`11111`

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

- Write the result to the output. Output:
`111110`

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

- Write the result to the output. Output:
`1111101`

**1**

- Take the second bit of the input and XOR it to the previous bit of the input.
**Step 4:**So, our final gray code result is:`11111011`
