- 1 Tonełada ecuivałente de carbón = 29.300.000.000 joule = 8.138,9 kilowatt ora.
Co aprosimasion, on joule el xe ła quantità de energía nesesària par tirar sù on kilogramo a na altesa de 10 cm da ła superfise de ła Tera.
Intrà i multipli del joule se połe catar:
- il kilojoule (kJ), che ecuivałe a 1000 joule (10³ J)
- il megajoule (MJ), che ecuivałe a 1000 kilojoule (106 J)
- il xigajoule (GJ), che ecuivałe a 1000 megajoule (109 J)
- il terajoule (TJ), che ecuivałe a 1000 gigajoule (1012 J)
- il petajoule (PJ), che ecuivałe a 1000 terajoule (1015 J)
