- Devine formula (1974) — Originally for drug dosing, now widely used. Male: 50 kg + 2.3 kg per inch over 5ft. Female: 45.5 kg + 2.3 kg per inch over 5ft.
- Miller formula (1983) — Male: 56.2 kg + 1.41 kg per inch over 5ft. Female: 53.1 kg + 1.36 kg per inch over 5ft.
- Hamwi formula (1964) — Male: 48 kg + 2.7 kg per inch over 5ft. Female: 45.5 kg + 2.2 kg per inch over 5ft.
