Jackson turbidity units to nephelometric turbidity units
Type a value in JTU to get it in NTU instantly.
95NTU
That's 1.9× as cloudy as a river after rain, while flood water is 5.3× cloudier. That is muddy: light barely penetrates.
Convert the other way: NTU to JTU
What it means
How cloudy is it?
Suspended solids and Secchi depth are correlations, not conversions: the same NTU from fine clay and from algae gives quite different figures.
The math
How to convert JTU to NTU
To convert Jackson turbidity units to nephelometric turbidity units, multiply by 19.
Example: 5 JTU × 19 = 95 NTU.
In the other direction, 1 NTU = 0.0526316 JTU.
