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 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 floor joist span capacity and estimate joist quantities from span, floor width, spacing, lumber properties, live load, and dead load. Construction Framing Calculator Estimate wall studs and plate boards for wood framing, including on-center spacing, end/corner studs, optional rough-opening allowances, waste, and material cost. 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. Construction Linear Feet Calculator Calculate freight linear feet from pallet dimensions and stacking, or convert square feet into running linear feet for flooring, trim, siding, and similar materials. 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. 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. Construction Plywood Calculator Estimate plywood sheets, usable coverage, and optional material cost from project dimensions, sheet size, and waste allowance. Education Quiz Grade Calculator Convert a quiz, test, or assignment score into a percentage and letter grade from either wrong-answer counts or earned-versus-possible points. Education Semester Grade Calculator Project a semester grade from term/marking-period scores and a final exam, then see the final exam score needed for a target semester grade. Household Solar Panel Calculator Estimate a home solar system size, panel count, roof area, annual generation, annual savings, installed cost, and simple payback period — or forecast yearly output from an existing array. Everyday Speed Calculator Solve for speed, distance, travel time, or running pace with one average-speed form and 11-unit speed conversions (mph, km/h, m/s, knots, ft/s, ft/min, mi/min, yd/s, yd/min, in/s, cm/s). Construction Stud Wall Framing Calculator Estimate studs, top and bottom plates, fire blocking, board feet, wall area, and lumber cost for one stud wall or a multi-wall framing project.
