Know Your Meter: Metric vs. Imperial
Navigating your energy bills starts with understanding how your gas usage is measured.
​
The type of meter you have — Metric or Imperial — determines how we calculate your gas consumption and, ultimately, your bill.
​
Let's break down the differences:
Metric Meters (m³)
-
Appearance: A newer model typically with digital or electronic displays
​
-
Measurement: Records gas usage in cubic meters (m³).
​
-
Calculation: We convert the cubic meters into kilowatt-hours (kWh) using a specific formula, taking into account the volume of gas used, the calorific value, and the conversion factor.
Imperial Meters (ft³)
-
Appearance: An older model, often with dials or a series of clock-like faces.
​
-
Measurement: Tracks gas usage in hundreds of cubic feet (100 ft³), indicated by a reading of '1' on the meter for every 100 ft³ used.
​
-
Calculation: The conversion from cubic feet to kWh includes additional steps to account for the imperial measurement, ensuring accurate billing.
Decoding Your Gas Bill: From Meter Reading to Payment
Navigating your energy expenses begins with a thorough understanding of your gas bill. It's more than just a monthly statement; it's a detailed record of your consumption and the cost associated with it. Using our Gas Bill Calculator, you can demystify the numbers, align your usage with your budget, and make empowered decisions about your energy use. Knowledge is power — particularly when it comes to managing your household expenses and finding ways to save.
Let's put theory into practice with real-life scenarios:
Metric Meters (m³)
Example:
Imagine your metric meter shows a jump from 1,000 to 2,000 m³. How does this reflect on your bill?
-
Calculate the Units Used:
2,000 m³ - 1,000 m³ = 1,000 m³ used.
-
Convert to kWh:
(1,000 m³×1.02264×39.2)÷3.6(1,000 m³×1.02264×39.2)÷3.6 = 11,096.53 kWh.
-
Calculate the Cost:
11,096.53 kWh \times 7 Pence/kWh = £776.76.
-
Standing Charge:
30 days \times 35 Pence/day = £10.50.
-
Total Estimated Bill:
£776.76 (energy usage) + £10.50 (standing charge) = £787.26.
Imperial Meters (ft³)
Example:
Your imperial meter reading goes from 100 to 582. What will your bill look like?
-
Calculate the Units Used:
582 units - 100 units = 482 units (or 48,200 ft³).
-
Convert to kWh:
(48,200 ft³ × 2.83 × 1.02264 × 39.2) ÷3.6 (48,200 ft³ × 2.83 × 1.02264 × 39.2) ÷ 3.6 = 154,314.85 kWh.
-
Calculate the Cost:
154,314.85 kWh \times 7 Pence/kWh = £10,801.84.
-
Standing Charge:
30 days \times 35 Pence/day = £10.50.
-
Total Estimated Bill:
£10,801.84 (energy usage) + £10.50 (standing charge) = £10,812.34.
These examples illustrate how readings translate into kWh and then into the actual cost, providing clarity on how your energy habits impact your finances.
