‘g’ is the engineering unit utilized for acceleration measurement and 1 g is defined as 32.1741 ft/sec2. An accelerometer that has a range of ± 10 g can measure acceleration between -321.7405 ft/sec2 and +321.7405 ft/sec2. The value of 1 g in meters is 9.8057 m/ sec2 and 386.0885 in/ sec2 in inches.
Different g Levels
One can experience different g levels in everyday life, while accelerating a car, during airplane takeoff, or riding on a roller coaster. Although people often do not make out how much the g level is, they can certainly sense it.
The estimates of different g levels commonly found in daily life and in familiar applications are listed out in the following table.
