For instance, if the focal length of your lens is 50 mm, select 50 mm in the calculator. The calculator will adjust for any focal length multiplier or field of view crop when the appropriate camera or film format is selected. Select your camera or film format. For digital "point and shoot" cameras, select "Compact digital". Select an f/stop. The list includes full, half, and one-third f/stops. The depth of field and hyperfocal distance are calculated each time one of the inputs changes. Tap the "HD" button to set the focus distance at the hyperfocal distance for the selected lens and f/stop.

Calculate the amount of asphalt you need and how much it will cost based on the chosen unit price. Unit System: Price per ton (optional): Required Asphalt: 0 ft³ (0 yd³) Asphalt Weight: 0 tons (0 lbs) How to use this calculator? Specify whether you want to use the metric or imperial system. Enter the length, width, and depth of the surface. If needed, change the default density of asphalt. If you want the calculator to also estimate the total price, enter the price per ton.How to calculate how much asphalt do you need?To calculate the required asphalt, Multiply the length by the width by the depth in the same units.Asphalt Required = length * width * depth Asphalt Required = 20 ft * 15 ft * (4 / 12) ft // We divide 4 by 12 because 1 inch is equal to 1/12 feet. Asphalt Required = 300 ft * (4 / 12) ft Asphalt Required = 100 ft³ To calculate the weight, multiply the asphalt required by the density. For example: 100 ft³ * 145 lb/ft³ = 14500 lbsWhat is the Asphalt Density?The density of asphalt refers to its mass per unit volume, typically measured in pounds per cubic feet (lb/ft³) or kilograms per cubic meter (kg/m³).The standard density of asphalt usually ranges from 138 lb/ft³ to 150 lb/ft³ (2,200 to 2,400 kg/m3³).In this calculator, you can specify your custom density to make the results adjusted to your needs.

Area to Cover (Square Feet): Desired Coverage Depth (Inches): Note: A standard bale of pine straw typically covers around 35-50 square feet at a depth of 2-3 inches. For deeper coverage, you may need more bales. When you’re planning to mulch a 2,500 sq ft garden area with a 3-inch depth, the pine straw calculator factors in the compression ratio (typically 2.5:1) and coverage rate (one bale covers approximately 50-75 sq ft at 1-inch depth).For a 500 sq ft flower bed requiring 2-inch depthArea: 500 sq ftDesired depth: 2 inchesCoverage per bale: 60 sq ft (at 1-inch depth)Calculation: (500 × 2) ÷ 60 = 16.67 balesRounded up: 17 bales neededSmall Garden Bed: Area: 200 sq ft Depth: 3 inches Calculation: (200 × 3) ÷ 60 = 10 balesLarge Commercial Space: Area: 3,000 sq ft Depth: 2 inches Calculation: (3,000 × 2) ÷ 60 = 100 balesResidential Landscape: Area: 1,500 sq ft Depth: 4 inches Calculation: (1,500 × 4) ÷ 60 = 100 balesTree Ring: Area: 50 sq ft Depth: 3 inches Calculation: (50 × 3) ÷ 60 = 2.5 balesPathway Coverage: Area: 300 sq ft Depth: 2 inches Calculation: (300 × 2) ÷ 60 = 10 balesPine Straw Calculation FormulaThe formula is: (Square Footage × Desired Depth) ÷ Coverage per Bale = Number of Bales NeededA slope factor of 1.2 for inclined areas. For example, a 400 sq ft sloped area at 2-inch depth:(400 × 2 × 1.2) ÷ 60 = 16 balesHow do I calculate how much pine straw I need?For L-shaped garden:Section 1: 20' × 30' = 600 sq ftSection 2: 15' × 10' = 150 sq ftTotal area: 750 sq ftAt 3-inch depth: (750 × 3) ÷ 60 = 37.5 balesRound up to 38 balesHow many bales of straw do I need to cover 1000 square feet?For 1,000 sq. ft. coverage:Thickness 2 inches: 14-16 balesThickness 3 inches: 20-22 balesThickness 4 inches: 25-28 balesFor 1000 square feet, the calculation varies based on desired depth. (1000 × 2) ÷ 60 = 33.33 balesRound up to 34 balesHow much does a bale of pine straw cost?Prices typically range from $3.50 to $7.00 per bale, varying by:Residential Purchase: $5-$6 per bale Commercial Bulk Order: $4-$5 per bale Premium Organic Sources: $7-$8 per baleWhat is Pine Straw?Pine straw consists of pine tree needles naturally shed and collected for landscaping. The most valuable types come from Longleaf, Slash, and Loblolly pines, known for
