Metric System Conversions and Prefixes

Gram ( $\text{g}$ ): The base unit of measurement for mass.
Meter ( $\text{m}$ ): The base unit of measurement for length.
Liter ( $\text{L}$ ): The base unit of measurement for volume.
Base Unit Exponent: Base units represent the central reference standard in the metric system with a scale factor of $10^0$ .

Giga: Represented by $10^9$
Mega: Represented by $10^6$
kilo: Represented by $10^3$
hecto: Represented by $10^2$
deka: Represented by $10^1$ (abbreviated using 1 letter)
base unit: Represented by $10^0$
deci: Represented by $10^{-1}$ , equivalent to the fraction $\frac{1}{10}$ or the decimal $0.1$
centi: Represented by $10^{-2}$ , equivalent to the fraction $\frac{1}{100}$ or the decimal $0.01$
milli: Represented by $10^{-3}$ , equivalent to the fraction $\frac{1}{1000}$ or the decimal $0.001$
micro-: Represented by $10^{-6}$ , equivalent to the fraction $\frac{1}{1000000}$ or the decimal $0.000001$
nano: Represented by $10^{-9}$ , equivalent to the decimal $0.000000001$
pico: Represented by $10^{-12}$ , equivalent to the decimal $0.000000000001$

Purpose: The stair-step method is used to convert units across different metric prefixes by shifting the location of the decimal point.
Directional Movement Rules:
- Moving up/left along the stair step shifts the decimal point to the left.
- Moving down/right along the stair step shifts the decimal point to the right.
Sequential Prefix Order (from larger to smaller values):
- Mega
- kilo
- hecto
- deka
- base unit
- deci
- centi
- milli
- micro-
