Scottish engineer and inventor whose improvements in the steam engine led to its wide use in industry ( 1736- 1819)

a unit of power equal to 1 joule per second; the power dissipated by a current of 1 ampere flowing across a resistance of 1 ohm

A unit of power or activity equal to 107 C. G. S. units of power, or to work done at the rate of one joule a second. An English horse power is approximately equal to 746 watts.

The electrical unit of power, or rate of work done by a current of one ampere with a potential of one volt.

The unit of electrical power, the power available when the current is one ampere and the electromotive force is one volt.

The practical unit of electrical activity, corresponding to the horse - power in mechanics; 746 watts are equal to one horse - power; from the Scottish inventor, James Watt ( 1736 - 1819).

Why should every schoolboy be taught that Watt was the inventor of the steam engine? – Concerning Animals and Other Matters by E.H. Aitken, (AKA Edward Hamilton)

We sailed on nearly due north, until the channel gave a sudden bend, just after we had passed the town of Greenock, a busy- looking place, with shipbuilding yards, and smoking chimneys, interesting to us because Watt was born here; near it we had seen on the opposite shore the village of Dunoon, a pretty watering- place. – A Yacht Voyage Round England by W.H.G. Kingston

In the same year Watt produced his successful steam engine, and a century has not elapsed since the first specimen of his skill was erected on this continent. – Opening Ceremonies of the New York and Brooklyn Bridge, May 24, 1883 by William C. Kingsley Seth Low Franklin Edson

Then James Watt invented the steam engine which used steam as a force acting on the piston. – Our Legal Heritage, 4th Ed. by S. A. Reilly

But as early as 1770 it was suggested by John Watt, and Stevens, the American inventor, actually gave a practical demonstration of its efficiency in 1804. Ericsson perfected it in 1836, and soon thereafter the British began building steamships with screws instead of paddle- wheels. – American Merchant Ships and Sailors by Willis J. Abbot

We must look to the Watt women as carefully as to the men; and these fortunately we find all that can be desired. – James Watt by Andrew Carnegie

Watt soon found out its faults, and made it work as it should do. – Lectures on Popular and Scientific Subjects by John Sutherland Sinclair, Earl of Caithness

Shortly afterwards, in consequence perhaps of this information, a project was formed at Sierra Leone of sending out a mission to Tombuctoo; but Mr. Watt, who was to have undertaken the journey, died; and the invasion of the colony by the French in September 1794, together with the destruction which followed, seems to have put a stop to expeditions of this nature. – The Journal Of A Mission To The Interior Of Africa, In The Year 1805 by Mungo Park

Inside of an hour he'd made a hand- sized, five- watt, wave- guide projector of waves of eccentric form. – The Pirates of Ersatz by Murray Leinster

Livingston and Fulton thus supplemented each other; Livingston possessed a monopoly and Fulton a correct estimate of the value of paddle wheels and, secondly, of Boulton and Watt engines. – The Paths of Inland Commerce A Chronicle of Trail, Road, and Waterway, Volume 21 in The Chronicles of America Series by Archer B.
