Bag liters are measured as a volume, specifically in cubic liters, similar to how cubic inches represent volume. This measurement is derived by calculating the internal space of the bag.
Understanding Bag Volume Measurement
The primary method for measuring a bag's capacity in liters involves its three spatial dimensions: height, width, and depth.
The Calculation Formula
To determine a bag's capacity in liters, you multiply its dimensions in centimeters:
Height (cm) x Width (cm) x Depth (cm)
The result of this multiplication will be in cubic centimeters (cm³). Since 1 liter is equivalent to 1,000 cubic centimeters, you then divide the total cubic centimeters by 1,000 to get the volume in liters.
Practical Example
Let's illustrate with the example of a Synic 30 bag, as provided in the reference:
| Dimension | Measurement (cm) | Measurement (inches) |
|---|---|---|
| Height | 50.8 | 20 |
| Width | 34 | 13.4 |
| Depth | 20.3 | 8.0 |
Calculation Steps:
-
Multiply the dimensions in centimeters:
50.8 cm x 34 cm x 20.3 cm = 35,062.24 cm³ -
Convert cubic centimeters to liters:
35,062.24 cm³ / 1,000 cm³/L = 35.06224 liters (approximately 35L, as stated in the reference).
This method provides a standardized way to quantify the internal storage capacity of a bag, allowing consumers to understand how much gear, clothing, or other items it can hold. While typically measured in centimeters for liter conversion, the equivalent volume can also be expressed in cubic inches (e.g., 20 in x 13.4 in x 8.0 in = 2144 cubic inches).
