Calculators

Calculates speed, distance, or time based on the other two values.

Calculates the static and dynamic compression ratios of an internal combustion engine. Static compression ratio is based on the engine's physical dimensions, while dynamic compression ratio considers valve timing.

Converts binary numbers (base-2) to their hexadecimal equivalents (base-16). Provides an insight into the relationship between these number systems.

This calculator converts any number into its equivalent representation in billions.

This calculator converts a force measured in pound-force (lbf) to newtons (N).

Calculates distances in Astronomical Units (AU), where 1 AU is the average distance between the Earth and the Sun.

Calculates the material removal rate (MRR) based on the volume of material removed and the machining time.

Calculates the minimum required size of a junction box based on the number and size of conductors entering the box.

Calculates the total R-value of insulation materials based on their individual R-values and thicknesses.

Calculates the number of floor joists needed and their total cost, based on room dimensions, joist spacing, and the cost per joist.
