What Is This Tool?

This tool helps you convert mass flow rates from milligrams per hour to kilograms per second, enabling easy standardization of very small mass transfer rates into the SI base flow rate unit.

How to Use This Tool?

  • Enter the mass flow value in milligrams per hour (mg/h).
  • Select the target unit as kilogram per second (kg/s).
  • Perform the conversion using the provided formula or conversion rate.
  • Review the results and apply them to your specific context.

Key Features

  • Supports conversion of mass flow rates specifically from mg/h to kg/s.
  • Includes definitions and typical applications of both units.
  • Provides example calculations for practical understanding.
  • Ideal for scientific, environmental, and engineering use cases involving very small mass flows.

Examples

  • Convert 10 mg/h to kg/s: 10 × 2.7777777777778e-10 = 2.7777777777778e-9 kg/s.
  • Convert 1000 mg/h to kg/s: 1000 × 2.7777777777778e-10 = 2.7777777777778e-7 kg/s.

Common Use Cases

  • Controlled microdosing in pharmaceuticals and lab-scale reactors.
  • Monitoring low-level emissions or evaporative losses of solvents and aerosols.
  • Measuring leak or permeation rates in packaging and microfluidic systems.
  • Specifying propellant mass flow in aerospace propulsion equipment.
  • Analyzing mass transfer in chemical processing and HVAC airflow.

Tips & Best Practices

  • Ensure steady and well-characterized flow rates during measurements.
  • Handle small numerical values carefully to avoid rounding errors.
  • Use the standardized SI unit (kg/s) for integration in engineering calculations.
  • Apply the conversion consistently when linking scientific data to industrial processes.

Limitations

  • Conversion results in very small values requiring high numerical precision.
  • Accuracy depends on steady and well-defined flow rates over time.

Frequently Asked Questions

What does milligram per hour (mg/h) measure?
Milligram per hour (mg/h) measures mass flow rate representing the transfer, emission, or consumption of one milligram of mass every hour.

Why convert from mg/h to kg/s?
Converting to kilogram per second (kg/s) standardizes small mass flow rates into the SI system for easier comparison and integration with engineering processes.

Where is this conversion commonly applied?
It is used in pharmaceutical dosing, environmental emission monitoring, chemical processing, aerospace propulsion, HVAC design, and microfluidic engineering.

Key Terminology

Milligram/hour [mg/h]
A unit of mass flow rate measuring one milligram of mass transferred every hour, used for very small mass transfer rates.
Kilogram/second [kg/s]
The SI derived unit of mass flow rate quantifying mass transferred per second across a cross-section.
