About the Btu

Facts & Uses

  • Core unit in U.S. HVAC, combustion, and fuel heat content tables; equipment capacity is typically rated in Btu/h (power) for load calculations and furnace/boiler sizing.
  • Common billing/market units: therm (100,000 Btu), MMBtu (106 Btu), and MBH (103 Btu/h) in gas utilities, pipelines, and energy trading.
  • Efficiency metrics convert directly: 1 kWh ≈ 3412 Btu; SEER and HSPF use Btu/Wh; AFUE/boiler efficiency often reported against Btu input.
  • Reference conversion anchor for engineering: 1 Btu (IT) ≈ 1055.06 J ≈ 0.000293071 kWh; useful for energy balances and heat loss/gain estimates.

Curiosities

  • Multiple historical definitions exist (e.g., IT Btu, mean Btu); modern U.S. practice typically standardizes on IT Btu.
  • Ton of refrigeration is a power unit equal to 12,000 Btu/h (not energy) and underpins A/C sizing conventions.
  • Notation can confuse: industry often uses MMBtu for million Btu (Roman numeral convention), while MBtu sometimes means thousand Btu.
  • Building analytics in the U.S. may cite energy use intensity (EUI) as Btu/ft²·yr for benchmarking envelopes and systems.

About the Kilowatt-hour

Facts & Uses

  • Primary electricity billing unit for homes, businesses, and EV charging; measured by smart meters and data loggers.
  • 1 kWh = 3.6 MJ (exact) ≈ 3412 Btu; also ≈ 1.341 hp·h for mechanical comparisons.
  • Used across energy analytics: load profiles, time-of-use (TOU) tariffs, net metering, and demand response programs.
  • Common for battery pack capacity (EVs, storage), PV generation summaries, and building energy dashboards.

Curiosities

  • Don’t confuse kW (power, rate) with kWh (energy, quantity); demand charges often bill peak kW, not kWh.
  • Historic UK term Board of Trade unit equals exactly 1 kWh.
  • Appliance energy labels estimate annual kWh consumption to compare efficiency across models.
  • In microgrids and off-grid systems, round-trip efficiency determines how many kWh stored are later delivered.
