Aqoonta guud
1 kcal: 1 kg ee heerkulka biyaha kor u kaca ama hoos u dhaca 1 ℃ cadaadiska jawiga caadiga ah, kulaylka la nuugo ama la sii daayo waa 1 kalori.
1 kiilogaraam oo baraf ah ayaa helaya 80 kalori
Kulaylka uumiga ee 1 kiilogaraam oo biyo ah waa 539 kalori
4 ℃ cufnaanta biyaha ayaa ah tan ugu weyn
