Acres Per Hour Calculator

Find field work rate from implement width and speed.

Working width

Speed

Field efficiency (%)

Acres per hour (ac/h) 5.818

Formula: ac/h = width × speed × 5280 ÷ 43560 × efficiency

Step-by-step with your numbers:

1. Values used:

2. Working width = 12

3. Speed = 5

4. Field efficiency = 80 %

6. Acres per hour = 5.818ac/h

Did we solve your problem today?

Estimate how fast you can cover a field.

The math behind it

acres/hour = width(ft) × speed(mph) × 5280 ÷ 43,560 × field efficiency.

12 ft at 5 mph, 80% → ~5.8 ac/h.

Field efficiency?

Accounts for turns and overlap — typically 70–85%.
