A program is being created to convert the data capacity of a storage device into a different measure - OCR - GCSE Computer Science - Question 5 - 2021 - Paper 1

To complete the function calculate, we must ensure that conversions for gigabytes, megabytes, kilobytes, and bytes are accurately represented. Here’s how:

function calculate(measurement, number)
    if measurement == "gigabytes" then
        value = number * 1024 * 1024 * 1024 * 8
    elseif measurement == "megabytes" then
        value = number * 1024 * 1024 * 8
    elseif measurement == "kilobytes" then
        value = number * 1024 * 8
    elseif measurement == "bytes" then
        value = number * 8
    else
        return -1
    endif
    return value
endfunction
