Recipe developers spend whole careers on clarity — scaled quantities, metric beside imperial — so that nobody ever has to think while holding an egg.
Keep the units and change the prefixes. Call for 6 dekagrams of sugar, 30 centilitres of juice and 0.25 kilograms of flour: every line is correct and none of it is usable. The cake came out fine, eventually, after the cook sat down with a pencil for twenty minutes and texted you three times. They have not asked for another recipe.
