### Engineering Notation

Engineering notation is similar to scientific notation, except for a few differences:

• The exponent is a multiple of three (for example, -3, 3, 6, etc.) ; and
• There can be one, two, or three digits to the left of the decimal point, rather than just one digit; to the right of the decimal, it can be as many as required.

Some examples of numbers written in engineering notation are as follows:

Notice how all 4 examples fit the pattern outlined above. Several examples of numbers being converted into engineering notation are demonstrated in the video below:
