Unit Conversion Practice
Generates a short set of unit conversion questions with their answers. Enter a family and how many questions you want, as "length, 10".
Generates a short set of unit conversion questions with their answers. Enter a family and how many questions you want, as "length, 10".
The families are length, mass, volume, time, and data. Add a third value to use as a seed, as "length, 10, tuesday", to get a different set.
The same input always produces the same worksheet, so you can hand out a seed and get the identical questions back later.
Use cases
- Making a quick conversion worksheet for a class
- Drilling unit conversions before a test
Examples
Three length questions
length, 3
{"family": "length", "seed": "length", "count": 3, "questions": [{"question": "4 mi = ? km", "answer": 6.4374, "from_unit": "mi", "to_unit": "km"}, {"question": "36 km = ? m", "answer": 36000.0, "from_unit": "km", "to_unit": "m"}, {"question": "52 yd = ? ft", "answer": 156.0, "from_unit": "yd", "to_unit": "ft"}]}FAQ
Is my data sent to a server?
Yes — the questions are generated on the server for this tool.
Why do I get the same questions every time?
The worksheet is generated from your input, so it is repeatable on purpose. Add a seed as a third value to get a different set.
How many questions can I ask for?
Between 1 and 25.
Are the answers exact?
They are rounded to four decimal places, so conversions such as miles to kilometres are accurate enough to mark against.
