How to Use the "Backpacking Water Calculator"

Backpacking trips can be fun and exciting, but they also require proper planning, especially when it comes to water consumption. The "Backpacking Water Calculator" is a useful tool that helps hikers determine how much water they need to bring on their trips. In this blog post, we will explore how to utilize the "Backpacking Water Calculator" and its significance in ensuring a safe and enjoyable backpacking experience.

Instructions for Utilizing the Calculator

The "Backpacking Water Calculator" has six input fields, and they include:

  • Number of Hiking Days - This field requires the number of days you will spend hiking.
  • Total Hiking Distance - This field requires the total distance you will cover during the hike.
  • Average Temperature - This field requires the expected temperature during the hike.
  • Elevation Gain - This field requires the total elevation gain during the hike.
  • Water Sources - This field requires the availability of water sources on the hike, whether there are no water sources, few water sources, or abundant water sources.
  • Water Consumption - This field requires the amount of water you expect to consume each day.

The output fields include:

  • Total Water Needed - This field calculates the total amount of water needed for the entire hike based on the input values.
  • Recommended Water Capacity - This field calculates the recommended water capacity for your backpack, based on the total water needed.

"Backpacking Water Calculator" Formula

The formula for calculating the total water needed is:

Total Water Needed = (Water Consumption * Hiking Days) + (Hiking Distance * Water Factor) + (Elevation Gain * Elevation Factor)


  • Water Factor = 0.5 for Few Water Sources or 0.25 for Abundant Water Sources
  • Elevation Factor = 0.75 for Few Water Sources or 0.5 for Abundant Water Sources

Illustrative Examples

Suppose you plan to hike for three days, cover 30 kilometers, expect an average temperature of 15°C, gain 2000 meters in elevation, have few water sources, and consume two liters of water per day. In that case, the total water needed will be 10.5 liters, and the recommended water capacity will be 11 liters.

Illustrative Table Example

The "Backpacking Water Calculator" is a valuable tool for backpackers who want to ensure they bring enough water for their trip. By inputting the required values, the calculator gives an accurate estimate of the total water needed and recommended water capacity. It is essential to plan adequately for water consumption during a backpacking trip, and the "Backpacking Water Calculator" is an excellent way to start.
