|Age||Conventional Units||SI Units (Conventional Units × 1)|
| Male||17–54 mEq/24 hr||17–54 mmol/24 hr|
| Female||8–37 mEq/24 hr||8–37 mmol/24 hr|
| Male||22–57 mEq/24 hr||22–57 mmol/24 hr|
| Female||18–58 mEq/24 hr||18–58 mmol/24 hr|
|Adult–older adult||26–123 mEq/24 hr||26–123 mmol/24 hr|
|Note: Reference values depend on potassium intake and diurnal variation. Excretion is significantly higher at night. Potassium excretion declines in older adults due to the decline in aldosterone levels, decline in renal function, and effects of commonly prescribed medications that inhibit the renin-angiotensin-aldosterone system.|
