Wood, Panel and Structural Timber Products - Mechanical Propertiesĭensity, fibre stress, compressive strength and modulus of elasticity of clear wood, panel and structural timber products. Wood Species - Moisture Content and Weight Seasoning is the name of the process where moisture content is reduced to the appropriate level for proposed use. Moisture content should be lower than 20 to stop fungal attack. Weight supported by a double or triple wood headers. Mass and density in the Imperial system Unit Converter After felling, timber will lose moisture to align itself with the atmospheric conditions. Soft and hardwood - the Janka Hardness scale. The density of wood versus moisture content.Ĭombustion heat values for wet and dry wood - Btu/pounds, kJ/kg and kcal/kg. Red Spruce, Longleaf Pine and Douglas Fir - moisture content and their compressive strength. Height of trees commonly used in towns and urban areas.Ĭombustion of wood and firewood heat values for species like Pine, Elm, Hickory and more. Nominal and minimum-dressed lumber sizes.īasic size, area, moments of inertia and section modulus for timber - metric units. Rough lumber, surfaced lumber (dressed), worked lumber, shop and factory lumber and yard lumber. Strength classes, bending stress and mean density of hardwood and softwood Softwood and Hardwood - Structural Strength Classes Machine Stress Rated (MSR) and Machine Evaluated (MEL) LumberĬalculate miter saw protractor angles for skirting and decorative mouldings work.Īllowable withdrawal load for nail and spikes. Weights of green, kiln dried and pressure treated lumber boards. Lumber and surface finishing abbreviations. Hardwood and Softwoods - Recommended Drill Bit Speeds Specific Weight and Specific GravityĪn introduction to density, specific weight and specific gravity. Material properties of gases, fluids and solids - densities, specific heats, viscosities and more.Ĭalculate angles with a straight board across carpenter's square.īoard feet is used as a volume measurement of lumber.ĭensities of common products - Imperial and SI-units.ĭensity vs. Shrinkage will occurs as a result of the moisture loss - typical 3-4% across the grain.ĭensities of solids, liquids and gases. Seasoning is the name of the process where moisture content is reduced to the appropriate level for proposed use. Density - (slugs/ft3) Weight-Specific Weight - (lb/ft3) (lb/US gallon) 32. Moisture content should be lower than 20% to stop fungal attack. Mass and density in the Imperial systemĪfter felling, timber will lose moisture to align itself with the atmospheric conditions.

View all measurement unit conversion calculators on the same page (may not work with all browsers requires Iframe). The calculators require that your browser has java script enabled.

Values lower than 0.001 will be displayed in the e-format e.g. Values of 10 000 or greater will be displayed in the e-format e.g. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). All results shown will be equivalent values. To use the measurement conversion calculators simply enter a number value into the desired field and click calculate.

For example, the specific gravity of water at 4 oC is 1.0 while its density is 1.0 gcm -3.ĬONVERSION CALCULATORS Convert between Different Units of Measurement Index of Unit Converters Because specific gravity is a ratio, it is a unitless quantity. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 oC. Sorry, your browser does not support JavaScript, which is needed to run this calculator Density, Specific Gravity Definition:ĭensity and specific gravity have very similar, but not quite identical definitions.ĭensity is the mass of material per unit volume. Note: conversions are only valid under the same conditions of temperature and pressure. DENSITY UNIT CONVERSION CALCULATOR DENSITY UNIT
