RV Propane Cooking Usage Calculator — How It Works

Overview

The RV Propane Cooking Usage Calculator helps RV campers, vanlifers, and outdoor cooks estimate how much propane they use for cooking and daily living. Instead of guessing when you’ll run out of propane, this tool calculates daily consumption based on your burners, cooking habits, and other propane appliances, then projects how many days you have remaining.


Core Formula

Propane to Energy Conversion

1 gallon of propane = 91,500 BTU
1 gallon of propane = 4.24 lbs

Cooking Propane Usage

Cooking BTU per meal = Total Burner BTUs × (Cooking Minutes ÷ 60)
Cooking Gallons per Meal = Cooking BTU per Meal ÷ 91,500
Cooking Gallons per Day = Cooking Gallons per Meal × Meals per Day

Example:
2 burners at 10,000 BTU each, cooking 30 minutes per meal, 3 meals per day:

Total BTU = 10,000 + 10,000 = 20,000 BTU
Cooking BTU per meal = 20,000 × (30 ÷ 60) = 10,000 BTU
Cooking gallons per meal = 10,000 ÷ 91,500 = 0.109 gal
Cooking gallons per day = 0.109 × 3 = 0.328 gal/day

Other Appliances

Appliance Gallons per Day = (BTU Rating × Hours per Day) ÷ 91,500
ApplianceTypical BTUTypical Hours/DayDaily Propane
Fridge1,500 BTU24 hours0.393 gal
Water Heater8,000 BTU1 hour0.087 gal

Total Daily Propane

Total Gallons per Day = Cooking + Fridge + Water Heater
Total Pounds per Day = Total Gallons × 4.24

Days Remaining

Available Propane = Tank Capacity × (Tank Level % ÷ 100)
Days Remaining = Available Propane ÷ Total Gallons per Day

Example:
20 lb tank (4.7 gal) at 80% full, using 0.5 gal/day:

Available = 4.7 × 0.80 = 3.76 gal
Days remaining = 3.76 ÷ 0.5 = 7.5 days

Editable Values (click to edit)

All numbered values are directly editable by clicking on them:

  • Burner BTU ratings — Default 10,000 BTU each (typical RV stove)
  • Cooking minutes per meal — Default 30 minutes
  • Meals per day — Default 3
  • Tank level — Slider or number input
  • Fridge BTU & hours — Default 1,500 BTU for 24 hrs
  • Water heater BTU & hours — Default 8,000 BTU for 1 hr

Practical Example

Setup: 2 burner RV stove (10,000 BTU each), standard 20 lb tank at 80%
