Calculators

Calculates the angle of refraction of light as it passes from one medium to another, using Snell's Law. This law describes how light bends when it transitions between two different substances with varying indices of refraction.

Calculates the absolute reticulocyte count, an indicator of bone marrow's production of red blood cells.

Calculates the simple interest earned on an investment or the simple interest owed on a loan.

Calculates the future value of an investment, considering the initial investment, interest rate, and investment duration.

Calculates the fabric requirements for a circle skirt based on waist circumference, skirt length, and optional fullness.

Simulates the population dynamics of a predator-prey system using the Lotka-Volterra equations. This model helps visualize how the populations of predators and prey change over time based on their interactions.

Calculate the volume of a rectangular box in cubic meters and convert between various volume units.

Converts a frame count into standard timecode format (HH:MM:SS:FF).

Calculates the angular extent of a scene captured by a camera based on focal length and sensor size.

Measures or estimates the time taken to respond to a stimulus.
