Calculators
Create and discover interactive calculators for various scenarios and measurements.
High School GPA Calculator
Calculates your Grade Point Average (GPA) based on your grades and the credit hours for each course.
QTc Calculator
Calculates the corrected QT interval (QTc) on an ECG, adjusting for heart rate, to assess the risk of arrhythmias.
HAS-BLED Score Calculator
Estimates the risk of major bleeding for patients on anticoagulation for atrial fibrillation.
Junction Box Sizing Calculator
Calculates the minimum required size of a junction box based on the number and size of conductors entering the box.
Wallpaper Calculator
Calculates the number of wallpaper rolls needed for a room based on the room's dimensions and wallpaper roll size.
Ladder Angle Calculator
Calculates the angle a ladder forms with the ground, given the ladder's length and the distance from the base of the structure.
Concrete Column Calculator
Calculates the number of pre-mixed concrete bags or the quantities of ingredients needed to mix concrete for columns, based on column dimensions.
Mixing Ratio Calculator
Calculates the required amount of each substance in a mixture based on a given mixing ratio and total desired amount.
Alligation Calculator
Calculates the alligation ratios needed to mix two solutions of different concentrations to achieve a desired intermediate concentration.
Molar Mass of Gas Calculator
Calculates the molar mass of a gas using the ideal gas law (PV = nRT), where molar mass (M) = mass / moles. This calculator rearranges the ideal gas law to solve for molar mass: M = (mass * R * temperature) / (pressure * volume).
