Mathematical Facts
Convert pennyweight to gram with the formula below. g ≈ dwt × 1.55517384. 1 dwt ≈ 0.00155517384 kg; 1 g ≈ 0.001 kg A pennyweight, symbol dwt, is a troy mass unit of 24 grains. Its name does not give the mass of a present-day coin. A gram reading is a mass measurement, for example for an ingredient or small component. It does not specify the volume occupied.
Why This Conversion Matters
This pair lets a workshop record in troy units be compared with another mass notation. It converts the total recorded mass without inferring the material’s composition. Exact unit relationships: 1 dwt = 24 gr; 1 g = 1,000 mg. The calculator uses the full stored factor and rounds displayed results to 12 significant digits. Display precision is not a guarantee of measurement accuracy.
Real-World Examples
Workshop troy mass records
A pennyweight, symbol dwt, is a troy mass unit of 24 grains. Its name does not give the mass of a present-day coin. This pair lets a workshop record in troy units be compared with another mass notation. It converts the total recorded mass without inferring the material’s composition. The examples below are illustrative recorded masses, not standard product sizes or prescribed quantities.
Examples:
- Workshop entry in pennyweights: 5 dwt ≈ 7.7758692 g
- Workshop entry in pennyweights: 20 dwt ≈ 31.1034768 g
Pro Tips:
- ✓Compare like-for-like total masses and preserve the troy unit label; composition needs separate information.
Quick Reference Table

Formula: g = dwt × conversion factor
Common Mistakes to Avoid
Treating a unit conversion as a purity or composition calculation
The same total mass is retained. Changing its unit does not reveal how much of any particular constituent it contains.
✓ Compare like-for-like total masses and preserve the troy unit label; composition needs separate information. 5 dwt ≈ 7.7758692 g.
Pro Tips
- ✓Keep dwt as the unit label; 20 dwt make one troy ounce, not one avoirdupois ounce.
- ✓Do not read a gram result as milliliters or spoonfuls; a mass-to-volume conversion also needs density.
- ✓Compare like-for-like total masses and preserve the troy unit label; composition needs separate information.
