localeTitle: 将摄氏温度转换为华氏温度
---

## Description
<section id="description">从摄氏温度转换为华氏温度的算法是以摄氏度乘以<code>9/5</code>的温度加上<code>32</code> 。您将获得一个可变<code>celsius</code>表示摄氏温度。使用已定义的变量<code>fahrenheit</code>温度，并将其指定为相当于给定摄氏温度的华氏温度。使用上面提到的算法帮助将摄氏温度转换为华氏温度。不要过多担心函数和返回语句，因为它们将在未来的挑战中涵盖。目前，只使用您已经学过的运算符。 </section>

```yml
tests:
  - text: <code>convertToF(0)</code>应该返回一个数字
    testString: 'assert(typeof convertToF(0) === "number", "<code>convertToF(0)</code> should return a number");'
  - text: <code>convertToF(-30)</code>应该返回值<code>-22</code>
    testString: 'assert(convertToF(-30) === -22, "<code>convertToF(-30)</code> should return a value of <code>-22</code>");'
  - text: <code>convertToF(-10)</code>应该返回值<code>14</code>
    testString: 'assert(convertToF(-10) === 14, "<code>convertToF(-10)</code> should return a value of <code>14</code>");'
  - text: <code>convertToF(0)</code>应返回值<code>32</code>
    testString: 'assert(convertToF(0) === 32, "<code>convertToF(0)</code> should return a value of <code>32</code>");'
  - text: <code>convertToF(20)</code>应返回值<code>68</code>
    testString: 'assert(convertToF(20) === 68, "<code>convertToF(20)</code> should return a value of <code>68</code>");'
  - text: <code>convertToF(30)</code>应返回值<code>86</code>
    testString: 'assert(convertToF(30) === 86, "<code>convertToF(30)</code> should return a value of <code>86</code>");'
