You can use the following POSIX-shellscript to convert Celsius to Kelvin:

```sh
#!/bin/sh
# Get temperature in Celsius from the user
echo -n "Celsius: "
read celsius
# Convert Celsius to Kelvin
kelvin=$(echo "scale=2; ($celsius + 273.15)" | bc)
# Print the result
echo "$celsius°C is $kelvin°K"
```
