What does microgram per liter measure?

Microgram per liter (µg/L) quantifies very small amounts of mass concentration in a fluid, commonly used for trace contaminants and low-level biomarkers.

When is teragram per liter used?

Teragram per liter (Tg/L) is applied to express extraordinarily high mass densities in astrophysical or high-energy-density physics models, not typical lab measurements.

Why is the conversion factor between µg/L and Tg/L so small?

Because 1 µg/L equals 1e-18 Tg/L, reflecting an 18 order of magnitude difference, the two units operate on vastly different density scales.

Select the to-unit as teragram/liter [Tg/L]
Click the convert button to view the equivalent value in teragram/liter
Use the converted result to compare or analyze mass densities across very different scales

Key Features

Converts density units from microgram/liter (µg/L) to teragram/liter (Tg/L)
Handles conversion across vastly different mass density scales
Browser-based and easy to use for environmental, biomedical, and astrophysical contexts
Provides precise conversion factor and example calculations
Supports applications ranging from trace contaminant detection to high-energy-density physics

Examples

500 µg/L equals 5.0e-16 Tg/L
1,000,000 µg/L is converted to 1.0e-12 Tg/L

Common Use Cases

Reporting trace-level contaminants in water monitoring and environmental assays
Expressing low concentrations of biomarkers or toxins in clinical and pharmacological studies
Representing extremely large mass densities in astrophysics models such as dense stellar remnants
Analyzing high-compression or high-energy-density physics simulations

Tips & Best Practices

Confirm the context of your measurement to ensure appropriate unit usage
Use microgram/liter for typical environmental and biological concentrations
Use teragram/liter only for extremely large mass densities relevant to astrophysics or theoretical physics
Be mindful of the large difference in scale due to the conversion factor of 1e-18
Double-check inputs when converting values to avoid misinterpretation between vastly different units

Limitations

Conversion factor spans 18 orders of magnitude, making Tg/L unsuitable for common laboratory or environmental measurements
Teragram/liter is predominantly used in astrophysical or theoretical physics contexts, not in routine chemical or biological testing
Due to scale incompatibility, direct comparison between these units requires careful interpretation
