The International System of Units (SI) — NIST Special Publication 330

National Institute of Standards and Technology (NIST). The SI Brochure (SP 330) is the definitive English edition of the BIPM SI tables. NIST’s edition lists the official constants and conversion factors tying inch-pound units to SI, which SwapUnits applies for length, mass, temperature, pressure, volume, and related conversions. See /standards/nist-si-tenfold for the complete decimal multiple/submultiple table. View source · View SI table

Fuel Economy Guide (Model Year 2024)

U.S. Environmental Protection Agency & U.S. Department of Energy. Describes how MPG, km/L, and L/100 km ratings are calculated for the U.S. Monroney label and how to interpret efficiency versus consumption metrics. View source

Alternative Fuels Data Center: Fuel Properties Comparison

U.S. Department of Energy. Lists gasoline energy content, used alongside the EPA MPGe consumer-label constant (33,705 Wh/gallon, about 8.90 kWh per liter) to convert between liquid-fuel efficiency (km/L) and EV metrics (km/kWh, kWh/100 km, Wh/km). View source

Petroleum-Equivalent Fuel Economy Calculation — 10 CFR 474.3

U.S. Department of Energy. EPA's consumer MPGe label uses a fixed 33,705 Wh/gallon energy-equivalence constant from five-cycle dynamometer testing, while a separate Petroleum Equivalency Factor for manufacturer CAFE compliance credit is being phased down from 82,049 to 28,996 Wh/gallon between model years 2010 and 2030 — two different constants for two different purposes.
