Unit Conversion Reference
All conversions are applied automatically by the platform.
GHG Emissions (base: kg CO₂-eq): tCO₂e = 1,000 kg | ktCO₂e = 1,000,000 kg | MtCO₂e = 1,000,000,000 kg
Energy (base: kWh): Wh ÷ 1,000 | MWh × 1,000 | GWh × 1,000,000 | MJ × 0.277778 | GJ × 277.778 | TJ × 277,778 | MMBTU × 293.071 | dth × 29.3071
Mass (base: kg): g ÷ 1,000 | t × 1,000 | kt × 1,000,000 | Mt × 1,000,000,000 | lb × 0.453592 | T (short ton) × 907.185
Volume (base: litres): hl × 100 | Ml × 1,000,000 | m³ × 1,000 | Mcf × 28,316.8 | MMcf × 28,316,800 | Bcf × 28,316,800,000 | gal × 3.78541 | bbl × 158.987 | MBbls × 158,987
Distance (base: km): mi × 1.60934 | nmi × 1.852
Units Not Supported & Why
The following units have been intentionally excluded:
gCO₂e (grams) A company emitting 100 tCO₂e would need to report 100,000,000 gCO₂e.
GtCO₂e (gigatonnes) Only used for national or global inventories, not corporate disclosures.
TWh (terawatt-hours) Relevant only for national grids or very large utilities; most companies report in MWh or GWh.
Mm³ (thousand cubic metres) Rarely needed; m³ and ML cover corporate requirements.
