Nursing Unit Converter
Convert common nursing units fast with a clean, mobile-friendly converter built for dosage math review, household-to-metric conversions, and NCLEX prep.
Enter a value above to see the conversion.
Common Nursing Conversions
1 g = 1,000 mg
1 mg = 1,000 mcg
1 kg = 1,000 g
1 kg ≈ 2.2 lb
1 L = 1,000 mL
1 tsp = 5 mL
1 tbsp = 15 mL
1 fl oz ≈ 30 mL
8 fl oz = 1 cup ≈ 240 mL
°F = (°C × 1.8) + 32
°C = (°F − 32) ÷ 1.8
37 °C = 98.6 °F (normal body temp)
1 inch = 2.54 cm
Intake & Output (I&O) Study Reminders
These household volume conversions are commonly used in I&O study problems and dosage calculations.
1 standard fluid ounce = 30 mL
1 measuring cup = 8 fl oz ≈ 240 mL
Ice chips count as half their measured volume for I&O
Example: 8 oz ice chips = 4 oz water = 120 mL
Do not round until the final step unless your instructor or exam directions say otherwise.
Why nursing unit conversions matter
Dosage math errors are among the most common — and most preventable — mistakes in nursing. A misplaced decimal or forgotten conversion factor can mean a 10× overdose or underdose. Unit conversion fluency is a foundational clinical safety skill.
The NCLEX tests dosage calculation and unit conversion as part of pharmacological and parenteral therapies. Being fast and confident with mg-to-mcg, mL-to-L, and kg-to-lb conversions saves time on exam day and reduces anxiety.
NurseZee's nursing unit converter gives you a clean, instant tool to verify your manual math, review common conversion facts, and build the automatic recall that makes dosage problems feel routine instead of stressful.
What you can convert here
Five conversion categories covering the units nursing students encounter most.
Mass / Medication Weight
mcg ↔ mg ↔ g ↔ kg. The conversions behind every dosage calculation.
Volume
mL ↔ L ↔ tsp ↔ tbsp ↔ fl oz. Metric and household volume for dosage and I&O problems.
Body Weight
kg ↔ lb. Essential for weight-based dosing and pediatric calculations.
Temperature
°C ↔ °F. Convert between Celsius and Fahrenheit for vitals and lab contexts.
Length
cm ↔ inches. Useful for wound measurements and growth charts.
