To calculate Exposure Value (EV), determine the ratio of the square of the aperture (N²) to the exposure time (t) and apply a base-2 logarithm. This calculation is essential in photography for determining the correct exposure settings. The Exposure Value Calculator is a practical tool for photographers aiming to balance aperture, shutter speed, and ISO…

To calculate the dead load of a structure, multiply the volume of the material (V) by its density (D). The Dead Load Calculator is a reliable tool for determining the static load of structural elements such as beams, slabs, roofs, and walls. Dead loads are the permanent, immovable forces acting on a structure due to…

To calculate the elevation angle for an antenna, you can use the formula that involves the distance between the two points and the height difference between the antenna and the target. The result will give the elevation angle required to aim the antenna correctly.   The Antenna Elevation Angle Calculator is used to calculate the…

Multiply flow rate (Q), differential head (DH), and specific gravity (SG), then divide by 3960 multiplied by efficiency (E) to calculate brake horsepower (BHP).   The Brake Horsepower (BHP) Calculator determines the power required to operate a pump, fan, or motor efficiently. BHP measures the actual output power, accounting for the mechanical and hydraulic loads. It’s…

To calculate the effective weight lifted during a push-up, multiply your body weight by a factor based on your repetition count. The Push Up Weight Calculator estimates the amount of weight your body lifts during a push-up. This tool is perfect for tracking your fitness progress, comparing push-ups to other exercises like bench presses, or…
