Orders of magnitude (length)

Orders of magnitude refer to the scale or size of a quantity in terms of powers of ten. When discussing length, each order of magnitude represents a tenfold increase or decrease in size. This concept helps to easily compare and understand very large or very small lengths by categorizing them into logarithmic scales. Here are some common examples of lengths from various orders of magnitude: 1. **10^-9 meters (nanometer)**: Scale of molecules and atoms.
