Oups! Grams or Ounces? Who needs the scales?

I do, definitely. But sometimes I use my great-great-aunt's recipe which mentions glasses, cups, tbs, tsp and so on. And the gorgeous lemon pie recipe I saw on my favourite food blog comes in ounces and pounds while my scales measure only grams. I won't probably go out and buy a new pair of scales! Digging in my cookbooks I collected the following  useful tips:

Spoons and Cups	Litres (ml)	Ounces	Grams
1 tsp (teaspoon)		1/6	5
1 tbs (tablespoon)		½	15
6 2/3 tbs (a glass of wine)	100 ml	3 ½	100
1 cup (16 tbs)	250 ml less 2 tbs	8	227
1 cup + 1 tbs	250 ml	8 ½	250
2 cups (1 pint)	450 ml	16 (1 pound)	454
4 cups (1 quart)	900 ml	32	907
4 1/3 cups	1 lt = 1000 ml	2.2 pounds	1000 = 1 kilogram

 Cups and ml equivalents

Cups	ml	Cups	ml
¼	56	1 ¼	283
1/3	75	1 1/3	300
½	113	1 ½	340
2/3	150	1 2/3	375
¾	168	1 ¾	400
1	227	2	450

Grams and ounces

Grams	Ounces	Grams	Ounces	Grams	Ounces
25	0.87	75	2.63	100	3.5
30	1.0	80	2.8	125	4.4
50	1.75	85	3.0	150	5.25

I printed it and pinned it on my fridge for a quick reference!
