Household Appliance Wattage Calculator Estimate daily and yearly electricity use and operating cost for a household appliance from wattage, or from amps and volts when wattage is not listed. Construction Board Foot Calculator Calculate board feet for milled lumber from thickness, width, length, and quantity, or compare standing-log yield estimates across Doyle, Scribner Decimal C, and International ¼-inch log rules. Construction Concrete Block Calculator Estimate CMU block count, mortar bags, sand, grout fill, and vertical reinforcement from wall dimensions, openings, block size, and waste allowance. Construction Concrete Calculator Estimate concrete volume for slabs, columns, tubes, strip footings, and curbs; convert the result to cubic yards, cubic meters, bag counts, weight, and optional material cost. Construction Concrete Mix Calculator Estimate concrete volume, ready-mix order quantity, and on-site cement, sand, aggregate, water, and bag counts from pour dimensions, mix grade, and waste allowance. Construction Deck Board Spacing Calculator Find an even deck-board layout that keeps both outside margins equal, then estimate linear feet, joists, and fasteners from the same board count. Construction Decking Calculator Estimate deck boards, linear decking, face screws or hidden clips, starter clips, fastener packs, and optional material cost for a deck surface. Education Final Grade Calculator Find the final exam score needed to reach a target course grade, project a what-if final score, and optionally derive your current grade from weighted graded items. Construction Floor Joist Calculator Check whether a common floor joist layout is within a planning span limit, then estimate joist count, hanger count, and lineal feet from the same dimensions. Construction Framing Calculator Estimate studs, plate boards, opening side-stud allowances, waste-adjusted buy counts, and optional material cost for wood wall framing. Business Freight Linear Feet Calculator Estimate LTL trailer linear feet from pallet count, loaded dimensions, stackability, mixed pallet sizes, and optional density-based freight class. Education Grade Calculator Calculate a weighted course grade from syllabus weights, see how much of the course is already banked, and estimate what average is needed on remaining work. Math Interquartile Range Calculator Calculate Q1, median, Q3, interquartile range, and 1.5 x IQR outlier fences from a pasted data set, with classroom and interpolated quartile methods. Construction Linear Feet Calculator Convert a square-foot area into the running linear feet of flooring, planks, trim, siding, or boards you need to buy, then add a waste allowance so you order enough in one trip. Construction Lumber Calculator Estimate boards to buy, board feet, lineal feet, waste allowance, and project cost for dimensional lumber orders. Construction Lumber Weight Calculator Estimate lumber weight from species density, actual dimensions or board feet, piece count, moisture content, and pressure-treated condition. Household Paint Calculator Estimate how many gallons and quarts of paint to buy for one interior room's walls, a ceiling, a whole exterior, or a primer coat — rounded up to purchasable cans so you never run short mid-coat. Education Percentage Calculator Solve four percentage questions in one form: percent change between two values, percent of a number, percent difference between two values, and what percent one number is of another.
