sci.UTM-zone-from-longitude Calculator
Calculates the UTM zone number from longitude: zone = floor((longitude + 180)/6) + 1, and central meridian = zone × 6 − 183°. UTM scale factor is 0.9996 at the central meridian, increasing to 1.0 at 180 km east/west — distortion is < 0.1% within each 6° zone.
Inputs
Longitude Deg
Reference formula or conversion factor shown for context.
Latitude Deg
Reference formula or conversion factor shown for context.
Results
UTM zone
Sample size or count used in the calculation.
central meridian (deg)
Sample size or count used in the calculation.
hemisphere
ISP (specific impulse) — rocket engine efficiency in seconds. Higher ISP means more thrust per kilogram of propellant consumed.
scale factor k₀
A dimensionless multiplier applied in the calculation.
EPSG code
Earnings per share — net income divided by shares outstanding. Rising EPS is positive if driven by real earnings growth, not just share buybacks reducing the denominator.
