Metric Ton per Second (t/s)
Definition: A very large metric mass flow unit expressing metric tons (1,000 kg) moved per second, sized for extreme bulk-material or fluid throughput.
History: A natural SI multiple built from the metric ton, used wherever kilogram-based figures would run into unwieldy six- or seven-digit numbers.
Current use: Occasionally used in large-scale bulk material handling and high-capacity pipeline modeling, where per-second tonnage better conveys the scale of flow.
Kilogram per Second (kg/s)
Definition: The SI derived base unit of mass flow rate — the kilograms of a substance passing a given point every second.
History: Formed directly from the kilogram and the second once both were established as SI base units, giving mass-transfer engineering a coherent reference unit.
Current use: The standard unit for mass flow rate in scientific literature, process engineering calculations, and SI-based industrial control systems.

About These Parameters
- Value
- The mass flow rate value you want to convert, expressed in the "From" unit. Accepts decimals.
- From Unit
- The unit your input value is currently measured in — a process control screen's kg/h, or a US boiler nameplate's lb/h.
- To Unit
- The unit you want the result converted into. Use the swap button to flip From and To instantly.
How Flow - Mass Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to kilograms per second. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Metric Ton per Second → Kilogram per Second: multiply by 1000. For example, 1 t/s × 1000 = 1000 kg/s.
Mass Flow vs. Volumetric Flow
This page covers mass flow — how much MASS passes a point per unit time. The site's separate Flow Converter covers volumetric flow — how much VOLUME passes a point per unit time. The two are related by density: mass flow = volumetric flow × density. For an incompressible liquid like water, density barely changes, so the two rates track each other closely. For a compressible gas, density shifts with temperature and pressure, so the same mass flow rate can correspond to very different volumetric flow rates at different points in a system — which is exactly why engineers designing combustion, turbine, and pipeline systems track mass flow, since it stays constant through a pipe of varying cross-section even when the volumetric flow rate does not.
Metric Ton vs. Short Ton
A metric ton (tonne) is exactly 1,000 kg, while a US short ton is 2,000 pounds — about 907.18 kg, roughly 9.3% lighter than a metric ton. The difference is small enough to overlook casually but large enough to matter in industrial contexts: a mining or aggregate operation quoting "500 tons per hour" means something meaningfully different depending on which ton is intended, and US equipment nameplates almost always mean the short ton unless explicitly labeled "metric." Always confirm which ton a US industrial spec sheet is using before comparing it to a metric figure.
Example
A mass flow rate of 1 t/s equals 1000 kg/s. For scale, a residential natural gas furnace burns fuel at only a few kilograms per hour, while a large industrial boiler or jet engine can consume fuel at rates measured in metric tons per hour.
Frequently Asked Questions
How many Kilograms per Second are in 1 Metric Ton per Second?
1 Metric Ton per Second (t/s) equals exactly 1000 Kilograms per Second (kg/s).
Why use mass flow instead of volume flow?
Mass is conserved through a system regardless of temperature, pressure, or pipe diameter changes, while volume is not for compressible fluids like gases and steam. Combustion, turbine, and process-control systems are built around mass flow because it gives a consistent, physically conserved quantity to balance and control, whereas volumetric flow can swing with conditions even when the underlying mass flow is steady.
What's the difference between a metric ton and a short ton?
A metric ton is exactly 1,000 kilograms. A US short ton is 2,000 pounds, equal to about 907.18 kilograms — roughly 9.3% lighter than a metric ton. US industrial equipment is conventionally rated in short tons unless explicitly labeled "metric ton," so it's worth double-checking which one a spec sheet or nameplate is referring to.
How accurate are these conversions?
Every conversion factor used here is the exact, internationally recognized relationship between the underlying mass and time units — results are limited only by floating-point display precision, not by rounded conversion constants.
