**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:
