What is an acre-foot (US survey)?

An acre-foot (US survey) is a volume unit representing the amount of water that would cover one acre to a depth of one US survey foot.

When should I use cubic miles for volume measurements?

Cubic miles are used for describing extremely large volumes such as lakes, reservoirs, or large geological formations.

Why is consistent use of US survey feet important?

It ensures conversion accuracy because the acre-foot definition relies on the US survey foot, differing slightly from the statute foot.

Browser-based tool accessible without installation
Ideal for scaling water volume measurements from local to regional levels
Supports volume conversions relevant to hydrology, geology, and environmental science

Examples

10 acre-feet (US survey) converts to approximately 2.9593e-6 cubic miles
1,000,000 acre-feet (US survey) equals about 0.29593 cubic miles

Common Use Cases

Measuring water stored in reservoirs and dams for effective management
Reporting irrigation water deliveries and agricultural water rights
Planning municipal or regional annual water supply and consumption
Describing volumes of large natural bodies such as lakes or ice sheets
Estimating water resources on a basin scale for regional planning
Communicating large-scale geological or earth-moving volumes

Tips & Best Practices

Ensure consistent use of US survey feet when measuring acre-feet for accurate conversions
Use this conversion for large volumes as cubic miles are practical at large scales
Be mindful that small errors in acre-feet may be negligible after conversion
Apply conversions within contexts like water resource management or geology

Limitations

Units differ in scale significantly; cubic miles are only meaningful for very large volumes
Small volumes converted may lose meaningful precision
Precision depends on consistent definitions of US survey feet versus statute feet
Not recommended for everyday or small volume conversions
