Formula
Formula
dwt = µg × 6.430149e-7
Multiply any value in micrograms by 6.430149e-7 to obtain the value in pennyweights (troy).
Worked example
Convert 2.00000e+6 µg to dwt.
- 01Start with 2.00000e+6 µg.
- 02Multiply by the conversion factor: 2.00000e+6 × 6.430149e-7 = 1.28603 dwt.
Result2.00000e+6 µg = 1.28603 dwt

FAQ
What is the conversion factor from µg to dwt?
1 µg equals 6.430149e-7 dwt. To convert, multiply the value in micrograms by 6.430149e-7.
How do I convert 1 µg to dwt?
1 µg = 6.43015e-7 dwt. For any value, multiply by 6.430149e-7.
How do I convert dwt back to µg?
Divide by the same factor — or equivalently, multiply by 1555174. So 1 dwt = 1.55517e+6 µg.
When would I need to convert microgram to pennyweight (troy)?
Mass conversions appear in material balances, reagent dosing, and reconciling vendor specifications across imperial/metric systems.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
