1 nano = 1 * 10^-9

Scientific notation makes it easier to express numbers of extremely small or large magnitude. For example, we could either say that something is .00000000068 meters long, or simply use scientific notation to write it as 6.8 x 10-10 meters. There is also an "engineering" notation which is similar to scientific notation, but all exponents are multiples of 3. This is so we can introduce prefixes such as nano, micro, kilo, giga, etc. The number 573000 would be written as 5.73 x 105 in scientific notation, and 573 x 103 in engineering notation.
The nano- prefix means "× 10^-9" → 1 nanometer = 1nm = 1 × 10^-9 m This can be abbreviated to 10^-9 m.
You can convert that to scientific notation in which the exponent is a multiple of 3. Use the closest powers of ten: either 10-6 and use the prefix "micro", or 10-9 and use the prefix "nano".

Sometimes engineers use either scientific or engineering notation, although you are correct that most of the time engineering notation is used. The reason for this the use if greek letter prefixes for quantities. Very often large and small quantities are expressed as micro, mega, giga, nano, and so on. These terms relate to engineering notation in multiples of 1000 or 1/1000. It is a very convenient shorthand not only in writing but also while speaking.
Well, isn't that just a happy little question! To write 450 nanometers in scientific notation, we first need to move the decimal point to the left until there is only one non-zero digit to its left. That gives us 4.5 x 10^2 nanometers. Just like painting a beautiful landscape, scientific notation helps us see the big picture in a clear and organized way.
