LPG vs Sui gas cost calculator: compare cost per MMBTU

Enter your monthly Sui gas use and what you pay per MMBTU to see how much LPG carries the same heat and what it would cost at the OGRA rate on file. Your bill, your numbers — not a quote.

Compare LPG with your Sui gas cost

Gas you use per month (MMBTU)Find this on your pipeline gas bill. If your bill shows only a different unit, use the MMBTU or energy line, or ask your gas company.What you pay for Sui gas (Rs per MMBTU)Divide the total amount on your bill by the MMBTU used. We do not assume a tariff because slabs, charges and taxes differ by bill.LPG rate (Rs per kg)Pre-filled with the OGRA-notified rate we have verified.

The heat in 2.00 MMBTU needs about

45.9 kg of LPG

About 22.9 kg of LPG per MMBTU. That is roughly 3.9 domestic 11.8 kg cylinders of gas.

LPG costs about Rs 6,407 per MMBTU at this rate. Enter your Sui gas price per MMBTU to compare.

Estimate only. It compares the cost of gas per unit of heat and assumes the same appliance efficiency on both fuels. It leaves out connection and meter charges, minimum bill, deposit, delivery and appliance conversion. Natural gas appliances need different jets and regulators to run on LPG; do not alter them yourself.

Estimate only

Results are rough planning figures from the numbers you enter and the assumptions shown. They are not a quote, a measurement, an engineering design or a safety check. For a written price send a request; the gas rate follows the OGRA notification (confirm the month on file when you order) and delivery and cylinder terms are confirmed before you agree.

How the comparison works

LPG kg = MMBTU × 1,055.06 MJ / LPG heating value (MJ per kg)
LPG cost = LPG kg × rate per kg
Sui gas cost = MMBTU × the price per MMBTU you enter

Pipeline gas prices depend on the slab and charges on your bill. We do not publish a Sui gas tariff here, so enter the figure from your own bill. When your pipeline supply is reliable it will often be the lower-cost fuel; LPG is the choice when there is no line, no pressure or no supply.

About the LPG rate

The tool uses the monthly OGRA consumer rate we have on file. Confirm it for your order date. Deposit and delivery for cylinders are separate from this energy comparison.

Frequently asked questions

Is LPG cheaper than Sui gas?

Usually not per unit of heat when you have a regulated pipeline connection. LPG makes sense where there is no connection, pressure fails in winter or supply is cut. Enter your own bill figures to see your case.

How do I find my Sui gas cost per MMBTU?

Take the total amount on your bill and divide it by the MMBTU used in the same month. That includes the charges you actually pay.

How many kg of LPG equal 1 MMBTU?

About 22.9 kg at 46 MJ per kg, because 1 MMBTU is about 1,055 MJ.

Can I run my Sui gas stove on LPG?

Not without conversion. A natural gas stove needs the right jets and a regulator for LPG. Ask a qualified installer.
