Use the unit you plan to select in the next field; the number has no unit on its own.<\/li>\n<li>Choose its current unit under <strong>From unit<\/strong>: m\/s\u00b2, ft\/s\u00b2, g (gravity), or Gal (Galileo).<\/li>\n<li>Choose the unit you want under <strong>To unit<\/strong>. You can select the same unit to leave the value unchanged.<\/li>\n<li>Read <strong>Converted Acceleration<\/strong>. The result includes the selected unit and is rounded to six decimal places.<\/li>\n<\/ol>\n<p>For example, to express an acceleration reported in feet per second squared as a multiple of standard gravity, select ft\/s\u00b2 as the From unit and g (gravity) as the To unit. You do not need to convert through m\/s\u00b2 yourself.<\/p>\n<h2>What acceleration units mean<\/h2>\n<p>Acceleration describes how quickly velocity changes with time. An acceleration of 1 m\/s\u00b2 means the velocity changes by 1 meter per second in each second, assuming the acceleration stays constant. The unit ft\/s\u00b2 describes the same kind of quantity using feet instead of meters. Because one foot is exactly 0.3048 meters, 1 ft\/s\u00b2 equals exactly 0.3048 m\/s\u00b2.<\/p>\n<p>The unit g expresses acceleration relative to <em>standard gravity<\/em>, defined as 9.80665 m\/s\u00b2. Thus, 1 g is an acceleration of 9.80665 m\/s\u00b2, while 2 g is twice that value. It is a reference unit, not a claim that the local gravitational acceleration is identical everywhere. In the default example, 9.81 m\/s\u00b2 is slightly greater than 1 g because 9.81 is slightly greater than 9.80665.<\/p>\n<p>Gal, named for Galileo, is a smaller acceleration unit: 1 Gal equals 1 centimeter per second squared, or 0.01 m\/s\u00b2. It can be useful when acceleration differences are small, including in some measurements of gravity. For scale, standard gravity equals 980.665 Gal. The calculator uses <strong>Gal<\/strong> as the unit symbol; it does not offer inches per second squared or any units beyond the four listed in its menus.<\/p>\n<p>A conversion preserves the size of a physical acceleration; it does not calculate acceleration from distance, time, or force. If you are working from mass and acceleration to find a force, use a <a href=\"https:\/\/wpcalc.com\/en\/converters\/force\/\">force converter<\/a> for the resulting force units. <a href=\"https:\/\/wpcalc.com\/en\/converters\/torque\/\">Torque<\/a> and <a href=\"https:\/\/wpcalc.com\/en\/converters\/pressure\/\">pressure<\/a> also have their own units and cannot be obtained by simply changing an acceleration unit.<\/p>\n<h2>Assumptions and practical tips<\/h2>\n<ul>\n<li><strong>Use a nonnegative magnitude.<\/strong> The Acceleration value field has a minimum of zero. If direction matters, keep track of it separately; this converter does not represent signed components or vectors.<\/li>\n<li><strong>Check what \u201cg\u201d means in your source.<\/strong> Here it always means standard gravity, 9.80665 m\/s\u00b2, not a location-specific measurement of Earth\u2019s gravity.<\/li>\n<li><strong>Keep rounding in mind.<\/strong> The displayed result is rounded to six decimal places. A very small nonzero conversion may therefore appear as zero, and converting a rounded result back may not reproduce every digit of the original value.<\/li>\n<li><strong>Match the source unit before interpreting the answer.<\/strong> Entering 9.81 with g selected under From unit means 9.81 g, not 9.81 m\/s\u00b2. That difference is nearly a factor of ten.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Convert an acceleration value between m\/s\u00b2, ft\/s\u00b2, standard gravity (g), and Gal.
