Calculators

Calculates the force of attraction between two objects with mass using Newton's Law of Universal Gravitation.

Calculates the change in position of an object, often using kinematic equations (SUVAT).

Calculates the Least Common Multiple (LCM) of two numbers. The LCM is the smallest positive integer that is a multiple of both numbers.

Performs the division of one number by another, showing quotient and remainder if applicable.

Finds the non-negative magnitude of a number (distance from zero).

This calculator uses the PHQ-2 and PHQ-9 questionnaires to screen for depression symptoms and assess their severity. The PHQ-2 is a quick screening tool, while the PHQ-9 provides a more detailed assessment.

Calculates the Sequential Organ Failure Assessment (SOFA) score, which assesses the severity of organ dysfunction in critically ill patients.

Converts dosages between different corticosteroid medications based on relative potencies.

Calculates the ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) from spirometry, aiding lung disease diagnosis.

Calculates the appropriate dosage of paracetamol (acetaminophen) for children based on their weight. This calculator assumes a standard concentration of 120mg/5mL for oral suspensions. Always consult with a healthcare professional before administering any medication.
