FAQ

I only want the conversions I use in the field.

You can filter down to starred conversions only. Pin them from quick chips, the current pair, or history entries.

How are decimals rounded?

You can choose significant digits or fixed decimals. The default is 4 significant digits, which is a practical field setting.

Can I use it offline?

After the page has been opened online once, the same device is designed for offline reuse. Actual behavior can still vary by browser and device.

Which gallon does gal/acre mean?

You can switch between US gallon and Imperial gallon. The spray category always shows the gallon type in the unit label.

How do I convert bushel/acre to kg/ha?

Because bushel weight changes by crop and grade, enter the test weight. Check the product label, public guidance, or contract specification before using the result.

Glossary

10a

Ten are. It equals 0.1 ha or 1,000 m² and is common in Japanese spray and fertilizer recommendations.

US gallon

1 US gallon = 3.785411784 L.

Imperial gallon

1 Imperial gallon = 4.54609 L. It is not the same as a US gallon.

bushel

A volume-origin unit whose weight conversion changes by crop and grade. You cannot convert it to mass safely without a factor.

Formulas

  • Converted value = input value × (from-unit internal factor ÷ to-unit internal factor)
  • L/10a -> L/ha uses ×10
  • kg/10a -> kg/ha uses ×10
  • bushel/acre -> kg/ha multiplies test weight(lb/bushel) × 1.120851156...

Notes

  • Crop-specific conversions such as bushel depend on crop and specification. Check the source of the factor before using the result.
  • The spray category always requires you to confirm whether the gallon is US or Imperial.
  • This tool gives reference values only. If a contract, label, or standard exists, follow that source first.
