## How to Convert a Number to Scientific Notation

Converting a number to scientific notation is easy.

### Question

What is 123,000 in scientific notation?

### Step-by-Step:

# 1

Place a decimal point to the right of the first digit of the number. In our example, the first digit of 123,000 is 1:

# 2

Ignore the 0s after the last non-0 digit.

**1.23** will appear in the answer.

# 3

Count how many digits there are after the first digit. (Don't ignore the 0s after the last non-0 digit this time).

There are **5** digits after the first digit.

# 4

Make the answer to **Step 3** (5) the exponent of a power of 10.

**10 ^{5}** will appear in the answer.

# 5

The number in scientific notation will consist of the number between 1 and 10 found in **Step 2** (1.23) multiplying the power of 10 found in **Step 4** (10^{5}).

### Answer:

We have converted the number to scientific notation:
