Explanation:

Step1: Convert 1 cm to inches

We use the conversion factor $1\ \text{cm} = 0.3937\ \text{in}$. The first line has marks at $0$, $\frac{1}{2}=0.5\ \text{in}$, $1\ \text{in}$, etc. $0.3937\ \text{in}$ is closest to the first box (between 0 and 0.5 in).

Step2: Convert 1 inch to cm

We use the conversion factor $1\ \text{in} = 2.54\ \text{cm}$. The second line has marks at $0$, $1\ \text{cm}$, $2\ \text{cm}$, $3\ \text{cm}$. $2.54\ \text{cm}$ is closest to the fifth box (between 2 cm and 3 cm).

Answer:

1. For 1 centimeter: Click the first box (between 0 and $\frac{1}{2}$ in.)
2. For 1 inch: Click the fifth box (between 2 cm and 3 cm)
