Conversion Formula:
For water, density ≈ 1 mg/mL, so:
\[ mL/hr ≈ mg/hr \]
| From: | To: |
The Mg/Hr to Ml/Hr conversion calculates the volumetric infusion rate (mL/hr) from a mass-based infusion rate (mg/hr) using the substance's density. For water, the density is approximately 1 mg/mL, making the conversion straightforward.
The calculator uses the conversion formula:
Where:
For water: Since water's density is approximately 1 mg/mL, the mL/hr rate will be numerically equal to the mg/hr rate.
Details: Accurate conversion between mass-based and volumetric infusion rates is crucial for proper medication administration, especially in IV therapy where infusion pumps are typically programmed in mL/hr.
Tips: Enter the mg/hr value (must be > 0). For substances other than water, enter the density in mg/mL. Leave density at 1 for water-based solutions.
Q1: Why is density important in this conversion?
A: Density relates mass to volume. Different substances have different densities, so 1 mg of one substance may occupy a different volume than 1 mg of another.
Q2: When can I assume density = 1 mg/mL?
A: For water and dilute aqueous solutions, density is approximately 1 mg/mL at room temperature. For other substances or concentrated solutions, use the actual density.
Q3: How does temperature affect the conversion?
A: Density changes with temperature. For precise work, use density values measured at the actual temperature of the solution.
Q4: Can I use this for non-water substances?
A: Yes, as long as you know the substance's density in mg/mL. Enter the correct density value for accurate conversion.
Q5: What about very viscous solutions?
A: While the calculation remains valid, very viscous solutions may require special consideration in actual infusion equipment.
