What Is This Tool?

This converter allows users to translate mass flow rates expressed in pounds per day into kilograms per second, facilitating standardization for various scientific, industrial, and environmental uses.

How to Use This Tool?

  • Enter the value in pound/day [lb/d] you want to convert.
  • Select the target unit kilogram/second [kg/s].
  • Click the convert button to see the equivalent mass flow rate.

Key Features

  • Converts mass flow rates between pound/day and kilogram/second units.
  • Supports applications in emissions reporting, process control, and propulsion systems.
  • Browser-based and easy to use with quick calculations.

Examples

  • Convert 10 lb/d: 10 × 0.0000052499116898148 = 0.000052499116898148 kg/s.
  • Convert 100 lb/d: 100 × 0.0000052499116898148 = 0.00052499116898148 kg/s.

Common Use Cases

  • Reporting facility emissions or fugitive releases in environmental monitoring.
  • Specifying chemical feed or dosing rates in process control systems.
  • Measuring mass flow in rocket engines, pipelines, and combustion equipment.

Tips & Best Practices

  • Ensure consistent time scales when comparing pound/day to kilogram/second values.
  • Handle very small numbers carefully to maintain numerical precision.
  • Use the conversion for stable flow rates averaged over time for accuracy.

Limitations

  • Pound/day measures flow over 24 hours, while kilogram/second measures per second, requiring attention to time scale differences.
  • The small conversion factor results in very small kg/s values that need careful numerical handling.
  • The conversion may not be accurate for highly variable or transient flow conditions.

Frequently Asked Questions

Why is the conversion factor between pound/day and kilogram/second so small?
Because pound/day measures mass flow over a full day and kilogram/second is a per-second rate, the conversion factor must account for the difference in time units, resulting in a small number.

Key Terminology

Pound per day [lb/d]
A mass flow rate unit expressing the amount of mass passing a point per 24-hour period in avoirdupois pounds.
Kilogram per second [kg/s]
An SI derived unit representing the mass flow rate of material passing a cross-section per second.
Mass flow rate
The quantity of mass moving through a given point or system per unit time.
