The Nurse's Bedside Calculation Companion

Weight-based dosages, IV drip rates, unit conversions, and shift totals: type them the way you would jot them on a chart and read the answers inline.

Built for nurses

Weight-Based Dosages

Type `patient weight = 70` and `dose per kg = 5`, then `total dose = patient weight * dose per kg` and the answer updates the moment either number changes.

Clinical Unit Conversions

Convert between kilograms and pounds, millilitres and fluid ounces, celsius and fahrenheit inline. Type `98.6 fahrenheit to celsius` and read the answer next to the line.

Concentrations and Dilutions

IV concentrations and dose adjustments read naturally: `0.9% of 500` for saline strength, or `250 - 15%` for a paediatric adjustment.

One Tab Per Patient

With Lifetime, keep calculations organised by patient or protocol. Rename tabs to stay oriented on a busy shift and switch between them without losing the previous numbers.

See It in Action

Weight-based dose

patient weight = 70
dose per kg = 5
total dose = patient weight * dose per kg

IV drip rate

volume mL = 500
duration hours = 4
flow rate = volume mL / duration hours

Shift medications

morning meds = 8
afternoon meds = 4
evening meds = 4
