What does one acre-foot (US survey) represent?

It is the volume of water covering one acre to a depth of one US survey foot, equal to 43,560 cubic US survey feet.

What is a ton register [ton reg] used for?

It is a maritime volume unit used historically to express a ship's internal capacity for commercial and regulatory purposes.

Can this conversion be used for modern shipping measurements?

Mostly no; ton register has been superseded in most international contexts by the 1969 Tonnage Convention measures, so this is mainly for historical or specific regulatory cases.

Examples

Convert 2 acre-foot (US survey) to ton register: 2 × 435.6026136105 ≈ 871.21 ton register.
Convert 0.5 acre-foot (US survey) to ton register: 0.5 × 435.6026136105 ≈ 217.80 ton register.

Common Use Cases

Measuring water stored in reservoirs and dams for water management.
Allocating irrigation water and reporting agricultural water rights.
Planning annual municipal or regional water supply and consumption volumes.
Expressing vessel internal volume in gross or net register tonnage for historical ship records.
Calculating port fees or canal charges referencing register tons.
Evaluating cargo-hold volume in older ship design and archival maritime documentation.

Tips & Best Practices

Ensure context-specific interpretation when applying land-based water volumes to maritime volume units.
Use this converter primarily for historical data or specific regulatory needs related to shipping.
Verify unit selections carefully to maintain accuracy in volume conversions.
Consult maritime documentation for understanding usage of ton register units.

Limitations

Ton register units have mostly been replaced internationally by more modern tonnage measurements defined in the 1969 Tonnage Convention.
Acre-foot volumes pertain to land water measurements and may not directly align with ship volume calculations without proper context.
