About Converting Picograys to Micrograys
Picogray and Microgray both belong to the radiation-measurement family, though radiation quantities fall into genuinely distinct categories: absorbed dose (gray, rad) measures energy deposited in matter, equivalent dose (sievert, rem) weights that for biological harm, and activity (becquerel, curie) measures how often a radioactive source decays — this page only converts between units of the same kind. Specifically: Picogray is 1e-12 gray units, and microgray is 0.000001 gray units.
Formula
micrograys = picograys × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 picogray equals 1e-12 base units, and 1 microgray equals 0.000001 base units, so dividing one by the other gives the direct picogray-to-microgray factor of 0.000001.
Simple example
1 pGy × 0.000001 = 0.000001 uGy
1 picogray = 0.000001 micrograys.
Real-world example
10 pGy × 0.000001 = 0.00001 uGy
10 picograys = 0.00001 micrograys.

Reverse conversion: Microgray to Picogray
0.000001 uGy × 1000000 = 1 pGy
0.000001 micrograys = 1 picogray.
picograys = micrograys × 1000000

Frequently asked questions
How many micrograys are in 1 picogray?
1 picogray equals 0.000001 micrograys, using the exact defined conversion factor rather than an estimate.
How do I convert picogray to microgray?
Multiply the picogray value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert microgray back to picogray?
Use the reverse factor: 1 microgray equals 1,000,000 picograys. You can also use the swap control in the converter above to flip the direction instantly.
What is a picogray?
Picogray (pGy) is a unit of radiation.
What is a microgray?
Microgray (uGy) is a unit of radiation.
Is the picogray to microgray conversion exact?
Yes. Both picogray and microgray are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
What's the difference between absorbed dose, equivalent dose, and activity?
Absorbed dose (gray, rad) measures the energy radiation deposits in matter. Equivalent dose (sievert, rem) adjusts that figure for how harmful different types of radiation are to biological tissue. Activity (becquerel, curie) measures how often a radioactive source decays, independent of how much dose a person actually receives from it.
