Convert Centimeters per second squared to Standard Gravities

The Centimeter per second squared (symbol: cm/s²) is a unit of acceleration. A CGS (centimeter-gram-second) unit of acceleration equal to exactly 0.01 m/s². Also formally called the 'Gal' (named for Galileo Galilei, originator of mathematical free-fall analysis ~1604), with the symbol 'Gal' used in published scientific notation. cm/s² / Gal is the standard working unit in gravimetry, geodesy, and Earth-physics research: regional variations in Earth's gravity field are reported in milligals (mGal = 10⁻³ Gal); high-precision spring gravimeters (LaCoste-Romberg, Scintrex CG-5/CG-6) and superconducting gravimeters (GWR Instruments iGrav) resolve microgals (µGal = 10⁻⁶ Gal); the GOCE / GRACE / GRACE-FO satellite missions map Earth's gravity field to a few µGal globally. Used in geophysical surveying to locate subsurface oil reservoirs (anomalies ~1-50 mGal), mineral deposits, underground voids and caverns, archaeological-feature mapping, and groundwater-table tracking. Earth-surface gravity variation between equator and pole is ~5,200 mGal (5.2 Gal), and free-air gradient is -3.09 µGal/cm of altitude.

It belongs to the metric measurement system.

Centimeters per second squared are commonly used in automotive testing, physics experiments, and aerospace engineering.

The Standard Gravity (symbol: g) is a unit of acceleration. The nominal acceleration of free fall at Earth's surface — exactly 9.80665 m/s² by CIPM Resolution 2 of 1901, formally adopted by CGPM 1948 and re-affirmed by BIPM SI Brochure through 2019. The 'g' or 'g-force' is the universal intuitive acceleration unit because it's a ratio to Earth-surface gravity, making numbers immediately interpretable for human-physiology and equipment-strain assessment. Reference values: fighter pilots routinely sustain 6-9 g in combat maneuvers (with G-suit assistance) per FAA flight-physiology research; F1 drivers peak ~5-6 g lateral in high-speed corners; Apollo astronaut peak g-load on Saturn V ~4.0 g during second-stage shutdown; SR-71 Blackbird structural-design ultimate g-load 3.0; commercial-airliner structural-design ultimate g-load 2.5 per FAR Part 25.337; bird-strike-impact peak ~3,000 g; automotive crash 30-80 g peak survivable with restraints per IIHS testing; baseball-bat impact ~10,000 g (instantaneous); top-fuel dragster launch ~7 g; a healthy untrained human can briefly experience 5 g without losing consciousness. Standard gravity is also the basis for kilogram-force and pound-force unit definitions.
