Converters

Convert grams to kilograms of CO₂(e) — divide by 1,000 (1 kg = 1,000 g). Bidirectional, with everyday small-footprint examples in grams and kg.

Convert kilograms of CO₂(e) to pounds — ×2.20462 (1 kg = 2.2046 lb). Bidirectional, with the metric-tonne vs US short-ton nuance and familiar examples.

Convert gigatonnes of carbon (GtC) to gigatonnes of CO₂ — ×3.664 (IPCC molar-mass basis; 1 GtC = 3.664 Gt CO₂). Bidirectional, with 3.664-vs-3.667 nuance.

Convert megatonnes to gigatonnes of CO₂(e) — divide by 1,000 (1 Gt = 1,000 Mt). Bidirectional, with the carbon-vs-CO₂ (GtC vs GtCO₂) unit trap explained.

Convert CO₂e into AI/LLM queries — about 0.14 g CO₂e per query (Epoch AI), so 1 tonne ≈ 6.9 million queries. Inference-only, with the wide range explained.

Convert CO₂e into Bitcoin transactions — about 488 kg CO₂e each, so 1 tonne ≈ 2 transactions. Live network data, the energy mix and how it’s derived.

Convert a CO₂e figure into return London–New York economy flights — 1.41 t CO₂e each (DEFRA, incl. radiative forcing). One-way and CO₂-only explained.

Convert a CO₂e figure into smartphone charges — the EPA equivalency, 12.4 g CO₂ per charge (≈80,650 per tonne, US grid). Bidirectional, basis explained.

Convert a CO₂e figure into tree seedlings grown 10 years — the EPA equivalency, 0.06 t CO₂ per seedling (≈16.7 per tonne). Bidirectional, basis explained.

Convert a CO₂e figure into gallons of gasoline burned — the EPA equivalency, 8.887 kg CO₂ per US gallon. US and UK gallons, both ways, basis explained.
