Scientific Notation Tools
Convert standard numbers to scientific and engineering notation, and perform exact arithmetic (+, -, ×, ÷) with normalized exponents.
Scientific Notation Converter
Convert decimal numbers to scientific notation (a × 10^b) and engineering notation with step-by-step mantissa normalization.
Scientific Notation Calculator
Perform addition, subtraction, multiplication, and division on numbers in scientific notation with exponent matching and normalization.
Significant Figures Calculator
Count significant figures, identify significant digits, and round numbers to N sig figs with scientific measurement rules.
Precision Tools for Exponential Mathematics
Scientific notation represents very large and very small quantities in compact exponential form (a × 10^b). From calculating planetary orbital trajectories in astrophysics to measuring atomic radii and electrostatic charges in quantum chemistry, exponential notation eliminates lengthy strings of trailing or leading zeros.
Our scientific notation tools provide seamless conversion between standard decimals, normalized scientific notation, engineering notation (with exponents in multiples of 3 matching metric prefixes), and programming e-notation, as well as exact multi-term arithmetic.
