**Physics Problem: Terminal Velocity of a Cupcake Liner**

A cupcake liner with the following properties is analyzed to determine its terminal velocity when dropped from rest:

- **Mass (m):** 0.397 grams
- **Cross-sectional area (A):** 42.3 cm²
- **Drag coefficient (D):** 0.644

**Environmental Constants:**

- **Acceleration due to gravity (g):** 9.806 m/s²
- **Air density:** 1.20 kg/m³

**Task:** Calculate the magnitude of its terminal velocity in meters per second (m/s). Enter the number only, without the unit. 

Note: Ensure to convert the mass to kilograms and the cross-sectional area to square meters when performing calculations.
