## About temperature APIs
As people prepare to go out for the day, one of the first things they do is check the temperature. Having this data allows them to bring the right gear to stay comfortable. People in places with dramatic temperature changes may rely on an application that sends them alerts of a sudden temperature drop. Websites and applications that share information about the outdoor temperature contact temperature APIs to receive current information.
## What is a temperature API?
Temperature APIs are a subset of databases with information related to weather. An API devoted to the outdoor temperature may include information about the current reading, historic temperatures or a forecast of predicted temperatures. Other temperature-related APIs serve as an easy way for an application to handle temperature conversions from the Celsius scale to the Fahrenheit or Kelvin scales.
## How do Temperature APIs work?
In a weather-related API, a developer’s application makes a GET request of the database that includes information about a location. The API returns temperature information from the past or present in JSON or XML format. Conversion APIs receive temperature data from the application and answer in the desired temperature scale.
## Who should use a Celsius API?
Celsius APIs have many applications. A developer could incorporate a request on an API in apps that revolve around local weather, outdoor activities or transportation. A programmer can make a simple enhancement to a newsfeed by adding a weather feature. Temperature conversion APIs are a helpful way to maintain websites that reach international audiences. By calling on a Celsius API with a conversion feature, the page will automatically use the preferred local temperature scale.
## Why is temperature information important?
Knowing the right temperature affects many basic aspects of daily life. Parents sending their children off to school want to know that the kids are dressed appropriately for the day. For industrial applications, the ambient temperature can affect machine performance. The outdoor temperature changes the way that ground crews prepare an airplane for a safe flight.
## Are there free Celcius APIs?
Much of the data found in a temperature API comes from government resources. For this reason, many APIs offer a freemium package for developers. For example, both the Storm Glass API and the Global Weather History API offer local information at no cost to applications that make fewer requests. A commercial application that makes many daily requests must pay a fee for access.

A powerful unit conversion tool. Convert currency (using an up-to-date international currency feed). Convert most known measurement types: imperial, metric, mass, length, temperature, time (and more). The convertor will accept full unit names as well as abbreviations (e.g. millimeter and mm)
The Storm Glass API gives developers access to global marine weather data from multiple sources using a single REST API.
The API returns marine weather forecasts for the next 7 days in hourly resolution. Forecasts include swell height, swell direction, swell period, wave height, wave direction, wave period, wind speed, wind direction, and air temperature.
Weather by location allows you to get weather information by ip, zipcode, lat lon coordinates. You can find weather information such as weather condition, current temperature, max temperature, min temperature, pressure, distance above sea level, humidity, wind speed & degree.
Get accurate historical weather from over 104,000 locations around the world. Daily weather measurements from 1763! Weather information includes: minimum & maximum daily temperature, snow fall, precipitation, evaporation and more!
