Convert the area, spray, and fertilizer units used in day-to-day field work from one compact card.

Handle ha↔acre, L/ha↔gal/acre, kg/ha↔lb/acre, 10a, and crop-specific bushel factors, then save, share, or revisit the conversion on the same page.

Starts with a 1 ha → acre example on first open Covers 10a, gallon type, and crop-specific bushel factors explicitly Keeps favorites and history, restores the last state, and works offline

Supported Conversions

ha acre converter / ha to acre converter
L/ha gal/acre converter / L/ha to gal/acre
kg/ha lb/acre converter / kg/ha to lb/acre
L/10a ↔ L/ha
kg/10a ↔ kg/ha
bushel/acre ↔ kg/ha (factor input)

How to Use

  1. Choose Area, Spray, Fertilizer, or Crop-specific.
  2. Enter a value, then choose the source and target units.
  3. If needed, adjust gallon type, rounding, significant digits, or Japanese area units in Settings.
  4. Review the result, reverse conversion, formula, and factors. Then copy, share, or star the combination.

Examples

80 kg/ha -> lb/acre

Output

80 kg/ha = 71.37 lb/acre

Crop-specific

Input

1 bushel/acre, corn 56 lb/bushel -> kg/ha

Output

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?

Open the page online once, then reuse it on the same device without a connection. Offline 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 (10a) equals 0.1 ha, or 1,000 m². It 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-based unit whose weight equivalent varies by crop and grade. Convert it to mass only after supplying the appropriate 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.
  • For spray rates, confirm whether the gallon is US or Imperial before comparing values.
  • This tool gives reference values only. If a contract, label, or standard exists, follow that source first.
