Convert units, fuels and emissions
Every figure says how exact it is and where it comes from — exact conversions and estimates are never mixed up.
An amount of fuel → its energy, mass and CO₂.

Energy
Same energy expressed in other units.

Gross calorific value · HHV/GCV
Mass
Volume
Emissions
CO₂ and CO₂e are separate — never derived from each other.
Energy density
Energy per unit of mass or volume.
Net calorific value · LHV/NCV
Assumptions
- density: assumed diesel density 832.361 kg/m³ at 15 °C (fuel-properties basis)
- heating value basis: energy on LHV/NCV basis, 9.905 kWh/L
- heating value basis: energy on HHV/GCV basis, 10.531 kWh/L

Exact vs. source-based — always distinct
Every result is tagged: an SI identity, a standard definition, a sourced value, or an estimate. We never dress an estimate up as exact.
How it works →Fuels & emissions, with the caveats
Density, heating values (LHV/HHV labeled), energy per litre/kg/m³, and CO₂ vs CO₂e kept separate — with the assumptions and warnings on display.

kW vs kWh, HHV vs LHV, barrel vs boe, why m³ of gas is not exact, why grid emissions depend on region and year — short, sourced explanations.

No invented numbers. Every non-exact factor cites a source. Missing data is marked not available — never guessed.
The pitfalls, surfaced. CO₂ ≠ CO₂e, LHV ≠ HHV, boe ≠ a physical barrel, kW ≠ kWh — the tool refuses to blur them.
Context over false precision. When a question needs a region, a year, or a duration, we ask — instead of returning a confident wrong answer.
