BTU to kWh Conversion Formula

To convert BTU to kilowatt hours, multiply the BTU value by 2.93072e-4 (0.000293072). One BTU equals 1055.06 joules and one kilowatt hour equals 3,600,000 joules, so the ratio works out to about 0.000293072 — or 3412.13 BTU per kWh in reverse.

BTU and Kilowatt Hours Explained

BTU (btu)

The British Thermal Unit (BTU) is the imperial heat unit: the energy to raise one pound of water by 1°F, equal to 1055.06 joules. In officially metric Canada, HVAC equipment still lives in BTU per hour — window air conditioners span 5,000 to 12,000 BTU/h, residential furnaces 40,000 to 120,000 BTU/h, and gas bills from utilities like Enbridge arrive in cubic metres and gigajoules that convert back to BTU. One BTU is roughly the heat of a burning wooden match.

Where it is used: Standard across Canadian and American heating, cooling, fireplace, grill, and fuel industries; also appears on EnerGuide labels, in ENERGY STAR Canada documentation and international LNG trading.

Origin: Descends from 19th-century British steam engineering; the International Table definition fixing it at 1055.06 J was standardized in the 1950s as imperial and metric systems needed a firm bridge — a bridge Canada still crosses every heating season.

Kilowatt Hours (kwh)

The kilowatt hour (kWh) is the billing unit of electricity: one kilowatt sustained for one hour, equal to 3,600,000 joules or 3412.13 BTU. Households consume it daily — a Canadian home averages about 30 kWh per day — and every meter from BC Hydro to Hydro-Québec counts it. For heating comparisons, the kWh is the common denominator that lets electric heat pumps, baseboard heaters and gas furnaces (converted from BTU) compete on one price sheet.

Where it is used: Universal in electricity billing across Canadian provinces, EV and battery specifications, EnerGuide appliance labels, and any cost comparison involving electric equipment.

Origin: Created by electric utilities in the 1880s as a natural billing unit of power multiplied by time; accepted for trade worldwide despite the SI system preferring joules.

When You Need BTU to Kilowatt Hours Conversions

Window Air Conditioner Running Costs

A bedroom unit rated 8,000 BTU/h moves 2.34458 kWh of heat per hour. Multiplying by your provincial electricity rate turns the EnerGuide label into a real monthly bill estimate before purchase.

Gas Furnace Versus Heat Pump Decision

Convert the furnace output first: an 80,000 BTU/h model delivers 23.4458 kWh of heat hourly. Comparing gas cost per gigajoule against electricity per kWh reveals which system heats cheaper in your province — a calculation that looks very different in hydro-rich Quebec than in Alberta.

EnerGuide and ENERGY STAR Reviews

Efficiency filings for Canadian compliance state capacities in BTU/h and consumption in kWh. Converting a pool heater's 150,000 BTU/h rating to 43.9608 kWh of heat keeps EnerGuide and ENERGY STAR Canada spreadsheets internally consistent.

Generator and Backup Power Planning

Standby generators are sized in kW while furnace blowers and AC loads appear in BTU/h. Converting a 48,000 BTU/h AC (14.0675 kWh per hour) into kW draw confirms whether a 20 kW generator carries a Toronto heat wave or an Ontario ice-storm outage.

Frequently Asked Questions

How many kWh are in 1 BTU?

1 BTU equals 2.93072e-4 kWh — about 0.000293 kWh. The more useful direction for HVAC work is the reverse: 1 kWh = 3412.13 BTU, since equipment ratings cluster in the thousands of BTU.

How many kWh is a 12,000 BTU air conditioner?

12,000 BTU × 2.93072e-4 = 3.51687 kWh of cooling per hour. That figure is heat moved, not electricity drawn — a modern unit with a 12 EER rating, common in Canadian apartments and condos, uses only about 1 kWh of electricity to do it.

How do I convert 100,000 BTU to kWh?

Multiply by 2.93072e-4: 100,000 × 0.000293072 = 29.3072 kWh. A hundred thousand BTU is about 0.1055 gigajoules — Canadian gas bills from utilities like Enbridge and FortisBC are priced in gigajoules and cubic metres, so 100,000 BTU is roughly a tenth of a GJ, just over 29 kWh of heat.

How many BTU is 1 kilowatt hour?

1 kWh equals 3412.13 BTU. This is the canonical figure on EnerGuide labels, ENERGY STAR Canada listings and heat-pump spec sheets — an electric baseboard heater drawing 1 kWh always releases 3412.13 BTU of heat.

Why do heat pumps list both BTU and kWh?

BTU describes heat delivered (a 36,000 BTU/h unit moves 10.5506 kWh of heat per hour) while kWh describes electricity purchased. Their ratio is the efficiency: moving 36,000 BTU on 3 kWh of input means the pump delivers 3.5 units of heat per unit of electricity — which is why cold-climate heat pumps now heat homes in Ottawa, Vancouver and even Winnipeg.

How many kWh is a gas furnace hour?

A typical 60,000 BTU/h furnace — right in the middle of the 40,000-80,000 BTU/h range found in most Canadian homes — converts to 60,000 × 2.93072e-4 = 17.5843 kWh of heat per hour. At 80% efficiency, about 14.0675 kWh actually reaches the ducts.

Is a BTU cheaper than a kWh?

As energy chunks, 3412.13 BTU equal 1 kWh, so a single BTU is a sliver of energy. Cost depends on fuel: in most Canadian provinces, a gigajoule of delivered natural gas (947,817 BTU, about 277.8 kWh of heat) costs less than the electricity needed to make the same heat, which is why gas furnaces stay popular in Alberta, Ontario and BC while hydro-rich Quebec leans electric.

How do I size an air conditioner using kWh?

Rule-of-thumb cooling loads run about 20 BTU per square foot (roughly 65 BTU per square metre): a 1,500 sq ft (140 m²) home in Toronto or Vancouver needs about 30,000 BTU, or 8.79217 kWh of cooling per hour. Divide by a seasonal efficiency of 3-4 to get expected electricity draw in kWh.

About BTU to Kilowatt Hours Converter

Our free online BTU to kilowatt hours converter provides instant, accurate energy conversions for HVAC sizing, heating comparisons, and utility analysis. In officially metric Canada, furnaces, gas fireplaces, air conditioners and backyard BBQs are still rated in BTU per hour, while electricity is billed in kilowatt hours by utilities like Hydro-Québec, BC Hydro and Toronto Hydro — and gas bills from Enbridge or FortisBC arrive in gigajoules. Every fuel-versus-electricity decision eventually requires bridging the units. Using the exact chain 1 BTU = 1055.06 J and 1 kWh = 3,600,000 J, this tool converts BTU to kWh (factor 2.93072e-4) or back (1 kWh = 3412.13 BTU) so you can price a furnace hour against a cold-climate heat pump, check an EnerGuide claim, or translate a gas bill in gigajoules into electricity terms.

Expert Tips for BTU to kWh Conversion

Memorize one number: 1 kWh = 3412.13 BTU. Everything else follows — 10 kWh = 34,121.3 BTU and 1 million BTU = 293.072 kWh.

Sizing shortcuts: 12,000 BTU/h = 3.51687 kWh of hourly cooling (one ton), 24,000 BTU/h = 7.03373 kWh (two tons), 36,000 BTU/h = 10.5506 kWh (three tons).

Gas bill translation: each gigajoule on an Enbridge or FortisBC bill (947,817 BTU) equals about 277.78 kWh of heat. If delivered gas costs less per GJ than 277.8 times your electric rate per kWh, gas heating wins on raw energy price.

Heat pump shopping: convert the rated heating output in BTU/h to kWh (× 2.93072e-4), then divide by the rated electrical input in kW to get the COP. A 36,000 BTU/h unit drawing 3 kW delivers 10.5506 ÷ 3 ≈ COP 3.5 — a figure worth confirming when applying for federal or provincial cold-climate heat pump rebates.

Annual energy audits: heating a Canadian home through a prairie winter — say 100 million BTU in Winnipeg — equals about 29,307.2 kWh of heat. Comparing that with your actual electric or gas billing reveals system efficiency losses immediately.
