Gunter's Chain
This is a surveyor's chain or Gunter's chain, an instrument used for measuring length. It comprises 100 pieces of straight metal wire, looped together end to end, and fitted with swivel handles. Its overall length is one chain (22 yards or 66 feet). The Gunter's chain was named after its inventor, Edmund Gunter (1581-1626), an English clergyman, mathematician, and astronomer. survey -

Equipment - Gold Scales, Late 19th / early 20th century
This type of balance scales allows precise measurements to be achieved by ensuring that the balance's fulcrum is essentially friction-free by attaching a pointer to the beam which amplifies any deviation from a balance position; and finally by using the lever principle, which allows fractional masses to be applied by movement of a small mass along the measuring arm of the beam. The standardization of the weights used – and ensuring traders used the correct weights – was a considerable preoccupation of governments throughout this time and inspections were held regularly. When the Weights and Measures Act was passed in Victoria in 1862 local inspectors were established throughout the colony to ensure accuracy particularly in the weighing of gold. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses.Set of small scales possibly from a travelling boxed set due to their small size, similar to those used in an apothecary and weighing gold. Scales have two round brass pans with a cross bar and chains and pointer central on the lever arm. At top of lever arm above pointer is a small leather tag from which to hold up the scales. city of greater bendigo commerce, making a nation exhibition, city of greater bendigo mining -

Forest Metriverter, Side Rule
Decimal currency was spectacularly introduced in an overnight overthrow on 14 February 1966, but it took another 8 years before metrication finally arrived in the forest and timber industry. Eventually, the measurement of logs and sawn timber changed from imperial, and excruciating, measures such as super feet of sawn timber, billets and cunits (100 cubic feet) of stacked pulpwood and hoppus log volumes to simpler cubic metres. Measuring firewood was a particular nightmare. For example, there were standard chords, stove cords, kitchen cords, running cords, face cords, thrown chords, fencing cords, country cords, long cords, raummeter or steres (1m x 1m x 1m). A standard cord of firewood had a volume of 128 cubic feet, measured as a pile 8 feet long, 4 feet high and 4 feet wide (3.624 m3). And how about this for confusing…. in Victoria, an imperial or long ton (by measure) of green firewood was a stack 5 feet long billets (2 axelengths at 2′ 6″ each), one axelength high (2′ 6″) and two axelengths long (5 feet) equalling 62.5 cubic feet. For added befuddlement, there were three different sorts of tons: Imperial tons or long tons, American short tons and metric tonnes (spelled with two n’s). Not forgetting that a cubic imperial ton of firewood (40 cubic feet) which equalled 1.133 cubic metre. The metrication process began in 1974 and was completed by 1976 but the transition was not without its challenges along the supply chain for foresters, overseers, logging contractors, sawmillers, hardware stores and builders alike. Timber lengths changed from feet to metres but were still sold in multiples of one foot or 0.3 m (1.8, 2.1, 2.4, 2.7 etc) whereas a menacing lump of 4-Bee-2 transformed into a rather less colourful 100mm by 50mm. Measurement and calculations of area also became so much easier in hectares rather than complicated acres, roods and perches. The Forest Metriverter slide-rule was issued by the Forestry and Timber Bureau to make metric conversions easier.Forest MetriverterRoss Pennyforest measurement, surveying, forests commission victoria (fcv)
