Science / Engineering Calculations

Instacalc loves science. It supports most imperial and SI units.

Scientific Calculator

• Note: Degrees are default: specify radians directly: sin(2pi rad)

Scientific Units

Instacalc works with most SI units, and you can do comparison as seen above.

• Units can be treated as variables: cm is 1 cm, and you can do 15 * cm
• Merge base units to compound with to SI: 15 kg m/s^2 to SI => 15 newton
• Split compound into base units to SIBase: 15 N to SIBase => 15 kg m/s^2
• Make compound units with space or multiplication: 15 kg m/s^2 or 15 kg * m/s^2
• See the predefined constants for physics constants (speed of light, gravity, etc.)
