Teho

Teho is a Finnish noun meaning power, strength, or intensity. In technical contexts, teho denotes the rate at which work is done, i.e., electrical or mechanical power. The unit commonly used is the watt (watti in Finnish). In physics and engineering, teho is defined as power, with the relation P = W / t, where P is power, W is work, and t is time. In everyday language, teho is used to describe the output or performance of engines, motors, appliances, and other devices.

In applied fields, teho often appears in product specifications to indicate performance. For example, an engine’s teho suggests how much work it can perform per unit time, while an electrical device’s teho can reflect its capacity to deliver energy. Distinctions are sometimes drawn between teho (power) and tehoversio or tehonkulutus (efficiency), which describe how effectively a device uses energy.

In statistics, teho (tilastollinen teho) refers to the statistical power of a test—the probability of correctly detecting a true effect. Higher teho means greater sensitivity and a lower risk of a Type II error.

As a name, Teho is also used in Finland as a male given name or nickname. It can stand on its own or function as a shortened form of other names.

Overall, teho centers on the concept of output or capacity, most prominently in science and engineering, while also appearing in naming and descriptive language within Finnish.
