Scientific Notation Complete Guide
Scientific Notation Rules
Format: C × 10^n where C is coefficient, n is exponent
Coefficient (C): 1 ≤ |C| < 10 (always between 1 and 10)
Exponent (n): Integer (positive, negative, or zero)
For numbers ≥ 10: Positive exponent (move decimal left)
For numbers < 1: Negative exponent (move decimal right)
Engineering Notation Rules
Format: C × 10^n where n is multiple of 3 (..., -6, -3, 0, 3, 6, ...)
Coefficient (C): 1 ≤ |C| < 1000 (1 to 999.999...)
Aligns with SI prefixes: k (10³), M (10⁶), G (10⁹), etc.
Preferred in engineering for unit compatibility
Easier for reading large/small numbers with metric prefixes

1 km = 1,000 m
Milli (m)
10^-3
1 mm = 0.001 m
Micro (μ)
10^-6
1 μs = 0.000001 s
Nano (n)
10^-9
1 nm = 0.000000001 m

Engineering Notation Tip:
Engineering notation uses exponents that are multiples of 3, making it easy to convert to SI prefixes. For example, 4.7 × 10^6 Ω = 4.7 MΩ (Megaohms).

Why Scientific Notation Matters:
Prevents errors with large/small number zeros
Simplifies multiplication and division
Standard format for scientific publications
Essential for computer representation of numbers
