Ships typical K values for 14 common components (gate/globe/check/angle/ball valves, 90°/45° elbows, tees, sudden contraction/expansion, sharp entrance/exit); choose a preset or supply a custom K. Supports n identical fittings in series. Returns head loss (m, ft) and pressure drop (Pa, kPa, bar). Density in kg/m³, g/cm³ or lb/ft³. - [Mulch Gravel Soil Bulk Bag Estimator](https://elysiatools.com/en/tools/mulch-gravel-soil-bulk-bag-estimator): Estimate how much mulch, gravel, topsoil, river rock, sand or compost a landscaping job needs. Enter the area shape (rectangle, circle, triangle or tapered bed/border), dimensions and depth, then pick a material from the built-in density table (or a custom density). The estimator returns volume (m³ / liters / yd³ / ft³), weight (kg / lb / tonnes), the count of 1 m³ or 1 yd³ bulk bags, small retail bag count, optional cost, plus depth and allowance warnings. Metric and imperial units supported. - [OZ to LB](https://elysiatools.com/en/tools/oz-to-lb): Convert ounces to pounds with configurable decimal precision - [Pipe Pressure Drop Calculator (Darcy-Weisbach)](https://elysiatools.com/en/tools/pipe-pressure-drop-darcy): Compute the Darcy-Weisbach major (friction) pressure drop in a straight pipe: ΔP = f·(L/D)·(ρ·v²/2) Pa and head loss h_f = f·(L/D)·v²/(2g) m. The user supplies the Darcy friction factor f (not the Fanning factor). Length in m/km/ft, diameter in m/cm/mm/inch, density in kg/m³/g/cm³/lb/ft³ — all normalised to SI internally. Returns ΔP in Pa, kPa and bar, and head loss in m and ft. Gravity defaults to 9.81 m/s² and may be overridden. - [Powerlifting Coefficient (DOTS / IPF GL) Calculator](https://elysiatools.com/en/tools/powerlifting-coefficient-dots-ipf-calculator): Compare a powerlifting total across four strength coefficient systems side by side: DOTS, Wilks (1994), IPF GL Points and Goodlift. Enter sex, body weight and three-lift total (squat + bench + deadlift) in kg or lb, and see each formula's points, coefficient, relative-strength tier and a progress bar showing how close the total is to each system's elite threshold. Complements the existing Wilks calculator by adding DOTS and IPF GL rather than replacing it. - [Pump NPSH (Net Positive Suction Head) Calculator & Cavitation Check](https://elysiatools.com/en/tools/pump-npsh-calculator): Compute the available Net Positive Suction Head (NPSH_a) of a pump and compare it against the required NPSH (NPSH_r) from the pump curve. Head-balance form: NPSH_a = (p_surface_abs - p_vapor) / (ρ·g) + H_static - h_friction. Surface and vapor pressures are absolute; H_static is positive for flooded suction, negative for suction lift. Returns margin (NPSH_a - NPSH_r), ratio (NPSH_a/NPSH_r) and a classification: safe, marginal (margin < 0.5 m), or cavitation likely. If NPSH_r = 0, only NPSH_a is reported. Pressure in Pa/kPa/bar/atm/psi, length in m/ft, density in kg/m³/g/cm³/lb/ft³. - [Stone to LB](https://elysiatools.com/en/tools/stone-to-lb): Convert stone to pounds with configurable decimal precision - [Ton to LB](https://elysiatools.com/en/tools/ton-to-lb): Convert US short tons to pounds with configurable decimal precision ## Related content - [Math](https://elysiatools.com/en/tags/math): Browse 502 online math tools for working with math operations, data, and files in your browser.
