How to convert US dry pecks to US dry gallons
The US dry bushel is 2150.42 cubic inches, divided into 4 pecks, 8 dry gallons, or 64 dry pints. These are capacities, not commodity weights; crop mass needs bulk density.
Use x for the value in pk (US), b for the intermediate value in m³, and y for the result in dry gal (US).
dry gal (US) = pk (US) × 0.00880976754172 ÷ 0.00440488377086
Worked examples
10 pk (US) ≈ 20 dry gal (US)
Step 1: (10 × 0.00880976754172) ≈ 0.0880976754172 m³.
Step 2: 0.0880976754172 ÷ 0.00440488377086 ≈ 20 dry gal (US).20 pk (US) ≈ 40 dry gal (US)
Step 1: (20 × 0.00880976754172) ≈ 0.176195350834 m³.
Step 2: 0.176195350834 ÷ 0.00440488377086 ≈ 40 dry gal (US).
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About US dry pecks
US dry pecks (pk (US)) measures volume dry under the conventions above. The base value in m³ is (x × 0.00880976754172), where x is the numerical value in pk (US). Factors shown here are rounded for display; calculations use the stored factor.
