Convert Nanosievert to Sievert

Type the number of nanosieverts that you wish to convert to sieverts.

1 nSv (nanosieverts) = 1e-9 Sv (sieverts)

How to Convert Nanosieverts to Sieverts

The nanosievert and sievert are both units of radiation dose. By definition, 1 sievert equals exactly 1000000000 nanosieverts. This means to convert nanosieverts to sieverts, you divide by 1000000000.

Formula

sieverts = nanosieverts ÷ 1000000000

Step-by-Step Example

Convert 5 nSv to sieverts:

1
Convert 5 nSv to sieverts

We need to convert nanosieverts to sieverts

2
Apply the formula

Since 1 Sv = 1000000000 nSv, divide by 1000000000

5 ÷ 1000000000 = 5e-9

Answer

5 nSv = 5e-9 Sv

About These Units

Nanosievert (nSv)

A nanosievert (nSv) equals 10⁻⁹ sieverts or 0.001 μSv. Used for extremely low radiation levels in environmental monitoring, clean room specifications, and background radiation surveys. Natural background: ~200-300 nSv/h typical.

Sievert (Sv)

The sievert (Sv) is the SI unit of equivalent dose, measuring biological effect of radiation exposure. Accounts for radiation type via quality factors. 1 Sv = significant health risk, 4-5 Sv = 50% fatality (LD50). Acute exposure above 0.5 Sv causes radiation sickness.
