In trigonometry, the gradian – also known as the gon (from Ancient Greek γωνία (gōnía) ' angle '), grad, or grade [1] – is a unit of measurement of an angle, defined as one-hundredth of the right angle; in other words, 100 gradians is equal to 90 degrees.

RAD即Radian的缩写，很多计算器上也简单地写成“R”，表示弧度制，即一个周角与半径为1的单位圆周长2π相等，把角度大小与实数对应起来。 GRA即Gradian的缩写，很多计算器上也简单地写成“G”，表示百分度制，即一个周角分为400份，每一份表示为1百分度。 在计算三角函数时，计算器不会自动地判断用户输入的数字是什么角度单位。 例如计算sin (30)，计算器不知道这个30到底表示30°，还是30 rad，又或是30 grad，因此必须人为地去指定一个角度单位，就像这样： 所 …

2019年6月19日 · css中的角度单位有：1、deg，度(Degress)，一个圆共360度；2、grad，梯度(Gradians)，一个圆共400梯度；3、rad，弧度(Radians)，一个圆共2π弧度；4、turn，圈(Turns)，一个圆共1圈。

2025年4月8日 · A gradian, also called a grad or a gon, is a unit of angular measure in which the angle of an entire circle is 400 gradians. A right angle is therefore 100 gradians. While some sources prefer "grad" ()'

无论是在学术研究、日常生活，还是在专业领域中，了解这两种角度单位的转换是非常重要的。 度 (°)到百分度 (grad)转换器。 度到百分度转换器。 如何将度 (°)转换为百分度 (grad)

By using these conversion formulas, you can easily switch between Gradians (grad) and Degrees (°) in angle measurements. It's essential to understand these conversions, especially when working with different angle systems or solving trigonometric problems. Remember, 1 grad is equivalent to 0.9°, and 1° is equal to 1.111111 grad.

2024年7月3日 · One gradian equals 0.9 degree, a unit used for measuring angles, especially in surveying and certain educational contexts. One gradian is equivalent to approximately 15.708 milliradians, used in ballistics, optics, and other precision scientific calculations.

Grade是梯度的单位。 梯度=9×角度/10. 弧度=角度×π/180. 梯度的本意是一个向量（矢量），表示某一函数在该点处的 方向导数 沿着该方向取得最大值，即函数在该点处沿着该方向（此梯度的方向）变化最快，变化率最大（为该梯度的模）。 梯度的应用： 设体系中某处的物理参数 (如温度、速度、浓度等)为w，在与其垂直距离的dy处该参数为w+dw，则称为该物理参数的梯度，也即该物理参数的变化率。 如果参数为速度、浓度、温度或空间，则分别称为速度梯度、浓度梯度、 …

The grad is a unit of plane angle, equivalent to 1/400 of a full circle, dividing a right angle in 100. It is also known as gon, grade, or gradian (not to be confused with gradient). One grad equals 9/10 of a degree or π/200 of a radian.

To convert a measurement in gradians to a measurement in degrees, multiply the angle by the following conversion ratio: 0.9 degrees/gradian. Since one gradian is equal to 0.9 degrees, you can use this simple formula to convert: degrees = gradians × 0.9. The angle in degrees is equal to the angle in gradians multiplied by 0.9.
