Monthly Usage Formula:
| From: | To: |
The Gas Per Month Calculator estimates natural gas consumption and cost based on daily usage patterns and fixed monthly consumption. It helps users budget and plan for their natural gas expenses.
The calculator uses the following formula:
Where:
Cost Calculation: Monthly cost is calculated by multiplying monthly usage by the price per therm.
Details: Accurate gas consumption estimation helps in budgeting, identifying energy efficiency opportunities, and understanding seasonal usage patterns for better energy management.
Tips: Enter daily usage in therms per day, fixed monthly usage in therms, and price per therm in dollars. All values must be non-negative numbers.
Q1: What is a therm?
A: A therm is a unit of heat energy equal to 100,000 British Thermal Units (BTUs), commonly used for natural gas billing.
Q2: How do I find my daily gas usage?
A: Check your gas meter readings over several days and calculate the average daily consumption, or divide your monthly bill by 30 and the price per therm.
Q3: What is included in fixed usage?
A: Fixed usage includes baseline consumption from appliances that run consistently, such as water heaters, pilot lights, and minimal furnace operation.
Q4: Why multiply by 30 instead of actual days?
A: Using 30 days provides a standardized monthly estimate. For precise calculations, use actual days in the specific month.
Q5: How accurate is this estimation?
A: Accuracy depends on the precision of your input values. Seasonal variations and unusual usage patterns may affect actual consumption.
