weighing, weight

These familiar words have for many centuries been ubiquitous in everyday speech and in the formal laws dealing with measure. They have, to some extent, been set apart from the word ‘measure’; the expression ‘weights and measures’ occurs in the title of every pertinent Act of the British parliament, and of the international office for metric measures (see BIPM), but the reason for that seems to have been the difference in the method of measurement for weight.

Weighing is the procedure routinely used to ascertain the (amount of) mass of something, yet it is repeatedly stressed that the gram, for example, is a unit of mass, not of weight. Technically the two are most certainly different; weight is a force, the product of mass and acceleration, the unit for which in metric is the newton. An object of a given (non-zero) mass at Earth's surface achieves its weight through being subject to gravitational acceleration. The actual acceleration causing weight is the true gravitational acceleration minus the amount of it consumed in providing the centripetal acceleration that keeps the object from flying off the rotating Earth. The latter is relatively trivial near the surface, even at the Equator.

Gravitational acceleration is inversely proportional to the square of the distance from the centre (approximately) of Earth, while centripetal acceleration is proportional to the distance from the axis of rotation. Hence, moving the object down a mine shaft increases its weight and moving it up a mountain decreases its weight (though such changes are minor). Elevating it further will reduce the gravitational acceleration; the concomitant impact on demand for centripetal acceleration will depend on circumstances. As centripetal acceleration is also proportional to the angular speed of rotation, flying fast above the surface can increase the demand considerably. A satellite at 600 km above the surface completing its orbit in two hours has a centripetal demand equal to the gravitational acceleration at that height, and hence it stays aloft. Likewise a satellite at 37 500 km orbiting in 24 hours stays aloft; if positioned above the Equator and travelling eastwards, like the points on Earth, such a satellite stays above the same point continuously (given a few small nudges from time to time to make it exactly so), so is said to be geostationary. The objects in the satellites, as well as the satellite itself, are then said to be ‘weightless’. In such a context, ‘weight’ is unequivocally a force.

The pound and its kin of BI and US-C, including the pennyweight and the hundredweight, were also seen as weight in the sense of force. However, physicists have long regarded them as units of mass, so now they have a wider public. The pound is routinely equated with 454.~ g, and the kilogram with 2.2~ lb, at any elevation and speed.

For centuries any measurement of weight employed a balance (scales, steelyard, auncel) of some form that actually compared an object of unknown weight with a selection of objects of supposedly known weight; such measurement actually compared masses and was independent of the local net gravitational acceleration. Usage of the phrase ‘weights and measures’ reflected this measurement by comparison rather than by reading a graduated scale. Only with the evolution of modern spring-loaded devices (ironically occurring after the introduction of metric with its emphasis on mass) did measurement of true weight become generally practicable - and these had adjustments to correct for altitude, subverting this. Now weight and mass can be measured just like electric current, etc., by using a meter, though balances continue to be used, from the finest laboratories to fitness centres.

Mass is identically inertia, the resistance of a body to acceleration, yet also the source of gravitational acceleration. Although it can be measured accordingly, the only generally practicable means for measuring it is via weighing. The spring-loaded weigh-scale measures the weight against the force of the spring. The balance, although its known weights are fixed only in terms of mass and its operation independent of the exact gravitational acceleration, cannot function without such acceleration; one truly balances the weights, but never knows their common weight.

See further under gravitational system.

It should be noted that the buoyancy of the surrounding medium affects the weight of an object. This was the essence of Archimedes' famous discovery, with water as the medium, but even the miniscule buoyancy of air has become significant in modern science. The 1963 definition of the BI gallon specified the volumic mass of the weights and of the air.

On the same principle that it is tempting fate to count things too closely, there was previously a prejudice in many people's minds about weighing newborn babies. First noticed by Chambers (1878: ii. 39), from Suffolk, although it was clearly well entrenched already, the belief is reported a number of times into the 20th century, and was not even extinct in the 1950s (Folk-Lore 68 (1957), 414). Opie and Tatem also record an earlier reference to the weighing of adults being considered unlucky, published in the British Apollo (7 Sept. 1709).

IN BRIEF: To use a scale to find out how heavy a thing is.

All the beautiful sentiments in the world weigh less than a single lovely action. — James Lowell (1819-1891).

Tutor's tip: Another word that sounds like "weigh" which means to use a scale to measure how heavy something is, is "way" which means a road or path.
