How to convert BTU/hr to watts. 1 BTU/hr = 0.29307107 W. So the power P in watts (W) is equal to the power P in BTUs per hour (BTU/hr) times 0.29307107 and is equal to the power P in BTUs per hour (BTU/hr) divided by 3.412141633: P(W) = P(BTU/hr) Ã 0.29307107 = P(BTU/hr) / 3.412141633. Example.
chroÂ·nolÂ·oÂ·gy. n. pl. chroÂ·nolÂ·oÂ·gies. 1. The science that deals with the determination of dates and the sequence of events. 2. The arrangement of events in time. 3. A chronological list or table.
Epoch: A division of the geologic time shorter than a period. Epochs are further divided into several ages. Generally, the geological timescale and the history of life is described in terms of periods, but in the case of the 65 million year long Cenozoic era, epoches are used instead (Paleocene, Eocene, etc).
