설명
The difference between 1 mm and 1 km is 6 orders of magnitude (10⁶). The observable universe spans roughly 93 billion light-years, while a proton is about 10⁻¹⁵ m — a difference of 41 orders of magnitude. Orders of magnitude are indispensable when comparing quantities too different for ordinary arithmetic.
