What picosieverts measure
Picosieverts (pSv) represent equivalent dose units. One unit equals 10^-12 Sv. The sievert is the SI unit used for radiation protection quantities such as equivalent and effective dose.
Reading the result in femtosieverts
Femtosieverts (fSv) represent equivalent dose units. One unit equals 10^-15 Sv. The sievert is the SI unit used for radiation protection quantities such as equivalent and effective dose.
Where this conversion helps
Change the scale of a dose value whose meaning and weighting have already been established. A unit conversion does not calculate biological effects, assess safety or substitute for radiation-protection expertise.
How the scale changes
The input unit has a factor of 1e-12 Sv; the output unit has a factor of 1e-15 Sv. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
