Explanation:

• For the first question: A micrometer ($\mu m$) is $10^{- 6}$ meters. Since $10^{-6}=0.000001$, the statement "A micrometer is equal to $0.000001$ m" is correct.
• For the second question: The International System of Units (SI) is the modern form of the metric system. The English unit system (e.g., inches, feet) and imperial system (related to the UK's historical units) are different from SI. There is no "math system" in the context of unit - systems.

Answer:

• First question: True
• Second question: metric system
