For choosing a battery, and for working out how long a generator or a mains charger will take. A 12 V 100 Ah battery on a 10 A charger is about 10 hours, less the losses.
How well a process actually ran. A lime neutralisation that only reaches 80% means you need more lime than the label says.
Cooling, spoilage, radioactive decay, drug clearance and declining yields.
Populations, investments, fermentation and anything that grows by a percentage each period.
Rough runtime for a battery bank before depth-of-discharge limits.
More accurate earthwork volumes than end-area averaging, especially on long cuttings.
Oven temperatures, animal temperatures, weather and old American books. Multiplication and addition beat a table every time.
Salt in a brine, protein in a feed, moisture in a crop, discount on a sale. Divide the percentage by 100 and multiply.

On a loan, an investment, or a hire-purchase agreement. The difference from simple interest is that the interest itself earns interest.
The rule behind a pressure cooker, a tyre, a gas cylinder and a fermenting barrel. Pressure rises with temperature and with the amount of gas, and falls as the volume grows.
Oilseed rape and grass are hungry for sulphur. Too little sulphur and the crop cannot use the nitrogen you have paid for, so the response to extra N is poor.

For working out whether a supply will carry a heater, a welder or a three-phase motor. See Three Phase And Single Phase.
The calculation behind a fertiliser plan. Subtract what the soil and the manure already give you, then convert to the product you are actually buying.
Long runs need bigger cable, not bigger fuses. Measure the run, use the table, and check the breaker size next.
