Scientific and engineering notation
Evaluate expressions with trigonometric functions, logarithms, roots, powers, constants, variables, and normal, scientific, or engineering result formats.
SCIENTIFIC & ENGINEERING CALCULATORS
Engineering calculators for scientific work, units, and technical formulas.
Use browser-based scientific and engineering tools for trigonometry, logarithms, powers, scientific notation, engineering notation, physical-unit conversion, and technical calculations.HOW TO USE THIS COLLECTION
Keep values, notation, and units consistent.
Engineering calculations often combine a numerical expression with a unit conversion. SolveGrid keeps these tasks connected: use Scientific Calculator for powers, roots, logarithms, trigonometry, constants, and engineering notation, then use Unit Converter for pressure, force, energy, power, torque, density, temperature, speed, frequency, and other unit families.
For circuit calculations, the DC Circuit Analysis Lab adds Ohm’s law, resistor networks, voltage dividers, RC transients, and two-node nodal analysis. Matrix and graphing tools remain one click away when a technical problem needs a coefficient system or visual check.

COMMON WORKFLOWS
What you can calculate in this section
Physical-unit conversion
Convert metric, imperial, SI, and technical units across length, area, volume, mass, pressure, force, energy, power, torque, density, temperature, and more.
Circuit and technical analysis
Calculate ideal DC resistor relationships, voltage dividers, RC responses, and a focused two-node nodal-analysis model with visible assumptions.
CHOOSE THE RIGHT METHOD
A practical three-step workflow
Write every value with its unit
Before calculating, identify the measurement unit and convert incompatible values into a common system. This prevents hidden factor-of-1000 and temperature-offset errors.
Select degree or radian mode
Trigonometric results depend on angle mode. Choose degrees for degree-based questions and radians for calculus, physics, or engineering formulas written in radians.
Use engineering notation for scale
Engineering notation uses exponents that are multiples of three, which aligns naturally with SI prefixes such as milli, micro, kilo, and mega.

COMMON QUESTIONS
Using scientific & engineering tools
What is the difference between a scientific calculator and a unit converter?
A scientific calculator evaluates numerical expressions and functions. A unit converter changes a measured value from one compatible unit to another. Many engineering problems require both steps.
Does the unit converter support engineering units?
Yes. It includes pressure, force, energy, power, torque, density, frequency, speed, acceleration, temperature, and other engineering and everyday unit families.
What is engineering notation?
Engineering notation writes powers of ten with exponents divisible by three. It is useful when working with SI prefixes and very large or very small technical values.
