how do you determine the difference between tons and yards in weight?

Question

I'm tring to figure how much gravel weights per ton compared to yards when I'm getting it from rock quarrys-quarrys weight by tons and nursiries sell it by the yards-which is the best way to buy?

Answer 1

weight per volume. The rock quarry can give you the weight per cu.ft. which can easily be converted into cu.yds. They need that info so they don't overload the trucks.

Answer 2

You can't do a simple conversion ... it depends on the type of gravel, the size of the stones and such, along with how wet it might be. The yard you're getting it from might be able to help, but I don't think there is a standard figure as the type of rock, the size of the individual stones, how wet they might be, and other factors might play a role in the weight.

Tons is a measure of mass, and yards is a measure of volume. The packing efficiency of the stones, which is determined by size and shape will make a difference in the weight per yard.

Answer 3

This site has a calculator
http://www.jackmassie.com/calc.html
which uses two different numbers depending on the size of rock 2835 and 4000 #/cubic yard which shows you how much it varies.
This site shows similar variation, although the numbers are in metric, you should be able to convert them if you wish

The quarry should be able to tell you exactly the pounds or tons per cubic yard. The nursery probably will not.

Answer 4

Length:
Inch [2.54 cm]
Link = 7.92 inches (see Chain for explanation)
Foot = 12 inches [30.48 cm]
Yard = 3 feet [91.44 cm]
Rod, Pole or Perch = 25 links = 5½ yards [about 5 metres]
Chain = 22 yards = 66 feet = 100 Links [length of a cricket wicket, about 20 metres]
Furlong = 10 chains = 220 yards [length of a furrow, about 200 metres]
Mile = 8 furlongs = 1760 yards = 5280 feet [a thousand Roman paces? – about 1600 metres]

Area:
Sq foot = 144 sq inches
Sq yard = 9 sq feet = 1296 sq inches [0.836 sq metre]
Sq Pole = 30¼ sq yards [often simply referred to as a Pole or Perch in land measurement]
Rood = ¼ acre = 1,210 sq yards = 40 sq poles
Acre = 4 roods = 10 sq chains = 4840 sq yards = Statute acre [0.40 hectare] [eg. a good-sized football pitch – but note that a Customary (or Saxon) acre was different, and that Scottish and Irish acres were different again]
Virgate = 30 acres [but varied in different districts - also called yardland]
Hide = 4 virgates [but really denoted the amount of land sufficient to support a family, and varied according to the locality or quality of the land]
Sq mile = 640 acres [259 hectares = 2.59 Sq Km]

Capacity [note, litre equivalents are for British Imperial measures]:
1 pint = 4 gills [0.568 litre]
1 quart = 2 pints [1.136 litre]
1 gallon = 4 quarts = 8 pints [4.546 litre]
1 peck = 2 gallons
1 bushel = 4 pecks = 8 gallons
